The IPX II pressure transmitter is specially designed for measuring pressure in explosive atmospheres (safety class, EEx ia IIC T4, Ta=-20°C to +80°C) as part of a larger overall system. It contains an integrated signal amplifier. The IPX II can be used in media temperatures up to 350°C. If the pressure transmitter is used in other applications, the safety and accident prevention regulations specific to that application must be followed.

When planning machinery and using the IPX II, follow the safety and accident prevention regulations that apply to your application, e.g.:

• EN 60204, Electrical equipment in machines.

• EN 292, Machine safety, general design guidelines.

• DIN 57 100 Part 410, Protection against electric shock.

• EN 50 014:1997, General Requirements

• EN 50 020:1994, Intrinsic safety apparatus

• EN50284:1999, Speical requirements for Group II Category 1G

Mounting and electrical connection of the PT must be done by specialists with EMC training, following all applicable regulations, and in

SAFETY

Operate only with an intrinsically safe, EMC compliant power supply with the following specifications when employing the pressure 4-20mA output:

Supply voltage max. 30 V DC Current output max. 125 mA Power output max. 900 mW Inductivity max. 0.26 mH Capacity max. 9.7 nF

Operate only with an intrinsically safe, EMC compliant power supply with the following specifications when employing the temperature 4-20mA output:

Supply voltage max. 30 V DC Current output max. 125 mA Power output max. 900 mW Inductivity max. 0 mH Capacity max. 52 nF

For PT that are explosion proof Class I, Division 1, Groups B, C & D, Class II/III, Division 2, Groups E, F and G. Power supply rating is 12-42 Vdc.

The Dynisco IPX II Series of Smart Pressure Transmitters are microprocessor based instruments that incorporate advanced software techniques and modern sensor design. New, proprietary sensor processing methods ensure the highest quality and reliability to meet Dynisco’s standards.

The IPX II Series is designed for applications that require high accuracy, even under wide variations in process temperature. With the capability for up to 6-to-1 span turndown, one pressure range can be used in several different applications, reducing spare parts inventory. And the IPX II Series’ remote digital communication utilizing the industry standard HART protocol allows transmitter parameter changes to be made from safe areas, increasing operator safety.

The IPX II Series of Smart Pressure Transmitters are characterized for process temperature effects, providing an optional linearized stable, temperature reading via 4-20 mA output. Figure 4-1 illustrates the operation of the transmitter in the form of a block diagram. The process temperature signal is available through the HART protocol. An optional dual LCD will display pressure or temperature measurements in real-time.

In addition to the standard analog output, the IPX II Series supports remote digital communications compatible with the HART Communicator (product of Emerson). The Model 275 can communicate with IPX II Series transmitters from the control room, at the transmitter site, or from any convenient junction box or wiring termination point in the measurement loop. The model 275 may be used to configure the IPX II Series of transmitters or to test the control loop.

The IPX II Smart Pressure Transmitter is a microprocessor-based device capable of measuring process pressure to within 0.15% of the specified range. It is compensated for temperature effects at the process end as well as the electronics end by using RTD’s and compensating software customized for each unit.

The IPX II Series can be broken down into two distinct subsections, mechanical and electrical. The following describes each in detail.

CHANICALCHANICAL

CHANICAL

The mechanical system (filled assembly) consists of a lower diaphragm, a filled capillary tube, and an upper diaphragm with a sputtered thin film strain gage. The filled assembly transmits pressure from the process to the strain gage diaphragm where it is converted to an electrical signal. The filled assembly isolates the electronics from the high process temperatures.

The lower diaphragm is the surface in contact with the media being measured. This diaphragm can be made from a choice of materials. The standard material is heat-treated 15-5 stainless steel. This has average corrosion and abrasion resistance and is similar to 17-4 stainless steel. Other materials are

FUNCTION

also available including Hastelloy C-276 which has excellent corrosion resistant properties (but is not good for abrasion). For other materials please consult the factory.

Behind the lower diaphragm is a capillary tube filled to the upper diaphragm. As the process pressure deflects the lower diaphragm, the fill is displaced through the capillary tube to deflect the upper diaphragm.

The upper diaphragm has a 5000 ohm thin film strain gage element deposited on it in the configuration of a Wheatstone Bridge. The deflection of the upper diaphragm causes a change in the resistance of the strain gage and hence a change in the balance of the bridge. The amount of imbalance is directly proportional to the applied pressure. This completes the translation of pressure applied to the lower diaphragm into a usable electrical signal.

CTRICALCTRICAL

CTRICAL

The low level output signal from the bridge is amplified via an instrumentation amp circuit. The amplified signal then goes to the input of the analog-to-digital (A/D) converter.

Once the microprocessor has the converted voltage input from the A/D converter, the compensation algorithms are executed. The unit is compensated for any errors introduced by temperature effects on the gauge, snout electronics, and the nonlinearities of the pressure measurement itself. The corrected digital signal is sent to a digital-to-analog (D/A) converter which modulates the current of the unit’s power supply between 4 and 20 milliamps for an output current proportional to the applied pressure.
