1. OUTLINE

1.1 Principle of Operation

When pressure is applied to a diaphragm in the resin pressure sensor (CZ-100P), force acts upon a pressure sensing element through a metal rod located near the diaphragm. The pressure sensing element used in CZ-100P has 4 gauges adhered to a metallic elastic body and connected to Wheatstone bridge. Each strain gauge made of metal resistance foil with small temperature coefficient slightly changes its gauge resistance due to strain occurring by the application of force to the elastic body. In this case, as shown in the attached diagram (Fig. 1), the elastic body is in such construction that by the application of force stretching strain occurs in R1 and R3, while shrinking strain in R2 and R4 to increase the gauge resistances of R1 and R3 and to decrease those of R2 and R4. These resistance changes are detected as bridge voltage change to generate the output proportional to the force applied. The output thus generated is input to the PCT-300 output converter which can finally output the DC voltages of 0 to 10 V, 0 to 10 mV, 1 to 5 V and 4 to 20 mA from its output terminals via a 3-stage amplifier circuit.

1.2 Features

 The detection of strain caused by the deformation of an elastic

metal body within its elasticity limit using the highly reliable strain gauge enables highly accurate pressure measurement.

 The dual construction of connecting pipe and pressure sensing

element portions extremely lessens output indication change caused by external transient temperature change.

 Calibration normally performed to a strain gauge sensor becomes

easy and accurate without monitoring the output due to the employment of the PCT-300 output converter.

3. MOUNTING

3.1 Pressure Sensors (CZ-100P)

3.1.1 Mounting cautions

 Mounting environment

 Ensure that no cooling pipes directly contact the pressure sensor

or connector, since the pressure reading accuracy may be affected or the connector may be damaged.

 Do not locate any heat source near the pressure sensor or directl y

expose it to heat. Otherwise, high-temperature deterioration of the sensor block may occur. If the temperature could rise in the strain gauge block located within the housing, cover possible heat sources with insulation materials.

 Do not use the pressure sensor under any of the following

environmental conditions:

- Where the sensor is exposed directly to cold air, warm air or hot air.

- Where temperature variations are large.

- Where the sensor is exposed to direct sunlight.

- Where the sens or is directly splashed with water or rain, or the humidity is high.

 Do not bring ma gnetic devices such as magnetic relays, etc. near

the pressure indicator. Also, keep power lines from the resin pressure sensor cable.

Page 3

 If the pressure sensor is used for screen changer operation, it may

suffer an impact during screen changer operation, causing sensor troubles. In such a case, carefully consider the position and direction when installing the sensor.

 Mounting pressure sensors  When the diaphragm at the end of CZ-100P and its surroundings

completely touch with its mounting hole, large indication error may occur. In this case, temperature may exert a large influence especially upon the zero point. Therefore, much attention should be paid when a mounting hole is drilled.

Do not wind sealing tapes, etc. round this section for preventing oil or resin leakage.

 When using a lead pipe cover, pay attention that the lead pipe

cover end does not directly touch the barrel. (Refer to the “ Exposed length at the bottom of the sensor outer case”)

Barrel

Lead pipe cover

 Prior to mounting the pressure sensor, check the appearance of

the diaphragm. If the diaphragm has a deformed or abnormal end, it needs to be repaired or re-calibrated. As there is a case where the diaphragm is already deformed by the application of overload when used previously, carefully check its condition before the pressure sensor is re-used.

Mount the sensor so that this block does not directly touch the barrel.

 Mounting hole  When mounting the pressure sensor, check its mounting hole

dimensions. (Do not overtighten its screw.)

 If resin or its carbide still remains in the mounting hole, this may

damage the pressure sensor. Therefore, prior to mounting the sensor, always remove any residue from the mounting hole.

 Check that the diaphragm surface does not protrude from the

inner wall of the barrel, since this may score the diaphragm surface with the screw, etc. If necessary, adjust the position between the diaphragm surface and the inner wall of the barrel using stainless steel gaskets, etc.

 For the loose nut type, resin leakage may occur more easily than

the fixed nut type, as the pressure sealing surface becomes wider. If any resin leaks through the mounting gap of the sensor, use copper gaskets (thickness: (thickness: the diaphragm surface and the inner wall of the barrel. (Copper Gasket: Included in only the Loose nut type)

mm) by taking into account the position between

t  2

mm) or aluminum gaskets

 Mounting direction  If the sensor is installed in the upright direction (Fig.1-A), it may be

affected directly by heat flow from heater or heat source (rising current of heated air). In such a case, the temperature of the strain gauge in the sensor may exceed an allowable maximum temperature of 150 C. In order not to exceed this limit temperature, it is necessary to keep the sensor outer cylinder surface at a temperature of less than 134 C (Fig.2). Conduct the following treatments.

1. In order to avoid heat flow, wind a heat insulating material round such a heat source (heater, etc.).

2. Further extend the length of the exposed lead pipe.

 In order to keep the specified sensor performance longer, it is

recommended that the sensor outer cylinder surface temperature be keep at less than 134 C.

 When the sensor is installed in the upright position, thermal e ffects

on the sensor may not sufficiently lessen even if the length of the exposed lead pipe is further extended. In this case, take measures of 1.

 The effect of heat flow lessens as the installing direction of the

sensor changes from the slanting direction (Fig.1-B) to the horizontal direction (Fig.1-C) in this order. In this case, take measures of 1 and 2 if necessary by checking the sensor outer cylinder surface temperature. (To the relevant manufacturer: It is recommended that the sensor be installed in the horizontal or slanting direction in order to lessen the effect of heat on the strain gauge.)

outer case

 Cases where the temperature of the strain gauge in the sensor

become less than 150 C is as follows:

 The effect of heat flow is small.  The sensor is installed in the upright position.  The diaphragm is at a temperature of 400 C.  The length of the exposed sensor outer cylinder is more than

70 mm. (Refer to below)

However, as the effect of heat flow from an actual extruder is serious, if there is no enough exposed section below the sensor outer cylinder even at a diaphragm temperature of less than 200 C, the operating temperature of the sensor strain gauge may exceed its limit. Therefore, check the temperature environment where the sensor is installed (by indirectly checking the temperature of the sensor outer cylinder surface), and take necessary measures to lessen the temperature of the sensor strain gauge by using a heat insulating material, if necessary.

 A lead pipe cover is mainly for protecting the exposed section below

If the temperature of the sensor outer cylinder surface exceeds 160 C, the outer cylinder surface changes its color from black to dark brown and then brown in this order. If it exceeds 180 C, the color may change to silver.

the sensor outer cylinder from being exposed to cold wind. Therefo re, do not install the sensor such that i t is embedded in the heat source (such as in the barrel or heater) together with th e lead pipe cover. This may heighten thermal conductivity from the heat source, resulting in a temperature increase in the sensor strain gauge.

3.1.2 Caution in removing pressure sensors

 Alw ays remove the sensor while resin is being melted, since

the diaphragm of the sensor may be damaged if the sensor is removed after the resin has hardened. If the sensor is re-mounted under this condition the repeatability may deteriorate.

 When removing the pressure sensor, remove it under the same

temperature as that during installation. Removing the pressure sensor under the different temperature as that during installation cause irregular engagement of the thread.

 If resin flows into the gap between the lead pipe and the mounting

hole, it may be impossible to remove the sensor even with the threads completely disengaged. In this case, if the sensor is forcibly removed using a puller, the sensor may be knocked when removed, damaging the diaphragm and reducing the accuracy. Slowly remove the sensor without knocking it.

and its surrounding section) after melting it by applying light heat to the side of the pressure sensing p art using a burner (Do not l et the temperature exceed 400 C). In addition, care should be taken not to scratch the pressure sensing block. If not, diaphragm damage or resin leakage may result.

3.1.3 Cautions during extruder cooling down

If the temperature is decreased while resin remains in the extruder with the pressure sensor installed, the diaphragm may be depressed and deformed by resin contraction, etc. As a result, a measurement error or pressure dead-band may occur. If the extruder is cooled down, completely remove all the resin remaining in the barrel, or remove the sensor. Especially take care for the low pressure sensor, as this effect becomes serious.

5. The other mounting bracket should be installed the same way as described in 3. and 4.

4. WIRING

To prevent electric shock or instrument failure, do not turn on the power until all wiring is completed. Make sure that the wiring is correct before applying power to the instrument.

4.1 Wiring Cautions

 The CZ-100P (sensor) connect to the PCT-300 (output converter)

using the 4-conductor shielded cable attached.

 The rated output of the CZ-100P (mV/V: Described on the

nameplate adhered) is obtained when standard cable length is 5 m. If cable length has been extended, conduct rated output correction referring to 6. CORRECTION (page 6).

 If the pressure sensor is used together with the output converter

(PCT-300), always connect a grounding wire to the equipment side. (Ground the grounding terminal.)

 Connect a grounding wire to the extruder.  For a heat-resistant glass covered cable, the cover is made of

fibers. Therefore, the electrical insulation may deteriorate if the cable is exposed to high humidity or conductive liquid (water, etc.) and cause a pressure indication error. For this reason, avoid underground wiring or wiring within electric conduits passing through humid areas as much as possible.

 This instrument with 24 V power supply is not provided with an

overcurrent protection device. For safety install an overcurrent protection device (such as fuse) with adequate breaking capacity close to the instrument.

－ Fuse type: Time-lag fuse (

and/or UL248-14)

－ Fuse rating: Rated current 0.8 A  For an instrument with 24 V power supply input, supply power

from “SELV” circuit defined as IEC 60950-1.

 A suitable power supply should be considered in end-use

equipment. The power supply must be in compliance with a limited-energy circuits (maximum available current of 8 A).

 Use the solderless terminal appropriate to the screw size.

Screw size: M3×6 Recommended tightening torque: 0.4 N Specified solderless terminals: With isolation Applicable wire: Solid/twisted wire of 0.25 to 1.65 mm

 Make sure that during field wiring parts of conductors can not

come into contact with adjacent conductive parts.

 Adjustment procedures

1. Check the rated output (mV/V) described on the nameplate of the CZ-100P (This output should be corrected when the cable is extended.) and then set that value on the rotary switch which is gain setter of the PCT-300.

2. The pressure reading zero point is adjusted by the zero adjuster in PCT-300. Perform this zero adjustment after the position installed with CZ-100P on the extruder reaches the desired temperature and is in the steady state after the lapse of a certain time. If an indicator is not available, adjust the zero point on the monitoring terminals using a circuit tester. In addition, perform the above adjustment after warming up for 20 minutes or more with the power switch of PCT-300 turned ON (power lamp lights) after wiring has been finished.

 When the gain setter and zero adjuster are set using small

screwdriver.

 When the sensor is provided with the gain selection

function (optional), the output value is doubled if the function is set to “2,” which is effective for increasing the reading at low-pressure. The valid range is within the output range of PCT-300, which corresponds to half of full-scale pressure.

 Turn the FILTER switch to the OFF side (100 Hz, 3 dB)

when quick response is required. The FILTER switch is turned to the ON side (10 Hz, 3 dB) prior to shipment.

6.1 Correcting Indication Error due to the Operating Temperature

The pressure indication error caused by the difference between the pressure sensor’s calibration temperature and the operating temperature can be adjusted using the instrument’s gain setting. The pressure indicator error [pressure sensor output (sensitivity) temperature affect] is within a “±0.2 % of span/10 ºC,” but the temperature affect can be corrected if necessary.

 Correction procedure

1. The rated output after the correction is calculated from the following correction equation and correction factor.

e1 = [1 + Correction factor  (T Calibration temp.)]  e0

e0: Rated output of the resin pressure sensor e1: Rated output after the correction T: Operating temperature Correction factor: Refer to below

6.2 Correcting Indication Error due to the

Connection Cable Length

RKC Instrument’s resin pressure sensor is calibrated for the standard cable length (5 m). Therefore, if the total length of the pressure sensor connection cable connected to the intrinsically safe circuit and non-intrinsically safe circuit side is other than 5 m, the resin pressure sensor indication value can be corrected using the instrument’s gain setting.

 Correction procedure

1. The rated output after the correction is calculated from the following correction equation and correction factor.

e1’ = e0’/[1 + K  (L  5)]

Set 1.499 to the gain setting portion of the instrument.

* For PCT-300, use the Gain Setter.

).

When anti-explosion specifications are required, use a cable with an allowable capacitance between the cable wires of 0.1F or less and an allowable inductance of

0.6 mH or less. The allowable inductance could be exceeded if the cable is

wound, so do not wind the cable when using it.

6.4 Correcting Indication Error due to the

Safety Barrier

A pressure indication error caused by the dispersion of our RZB-001 internal resistance value is within about 1 % of span. However, when this error needs to be lessened further, make the correction, if necessary. For this correction, the barrier correction factor B is used. No correction is required when the barrier correction factor B is “1.000.”

The barrier correction factor B is described on the nameplate of the RZB-001.
