User Manual EE300Ex Humidity / Temperature Sensor

2 Product description

2.1 General

The EE300Ex-M1 and the EE300Ex-M3 intrinsically safe sensors are intended for the measurement of relative humidity (RH) and temperature (T) or temperature alone, in the explosion hazard areas, in gas and dust up to Zone 0/20. The entire device can be placed in the explosion endangered area. The sensor may only be powered by an intrinsically safe power supply device or protective barriers. It features a 2 wire 4…20 mA design and has two individually scalable analogue outputs.

In addition to the measured RH and T, the EE300Ex-M1 calculates also the following parameters:

• Absolute humidity dv

• Wet-bulb temperature Tw

• Specific enthalpy h

• Dew point temperature Td

• Frost point temperature Tf

• Mixing ratio r

• Water vapour partial pressure e

Besides measurement in the air, the EE300Ex-M1 with ATEX or IECEx approval is also suitable for measuring water content (X) in ppm and water activity (aw) in isolation, lubrication and hydraulic oils.

3 Installation

3.1 General

The EE300Ex is certified according to ATEX 2014/34/EU Directive, IECEX Scheme, National Electrical

The use of the EE300EX in explosion hazard areas is only permitted under following atmospheric conditions:

 -20°C(-4°F) ≤T≤ 40°C(104°F)  0.8bar(12psi)≤p≤ 1.1bar(16psi)

air normally 21 % (v/v)

The EE300Ex may be employed beyond above atmospheric conditions range only observing EN 1127-1 and only in line with the manufacturer‘s instructions.

The EE300Ex may only be supplied by intrinsically safe power supply devices or via protective barriers. This applies also for the case when just the probe is located inside the explosion hazard area. The rules for wiring intrinsically safe electrical circuits according to EN 60079-14, EN 60079-25, IEC 60079-14, IEC 60079-25 (proof of intrinsic safety in the system description) as well as all applicable national regulations must be strictly observed. For the U.S., Canada refer to the Control Drawing M1_1309080 (page 51) and ANSI/ISA RP12.6.01, NEC and CEC.

The intrinsically safe circuitry shall include an overvoltage protection device if the analysis according EN 1127-1 reveals a risk of lightning strike. Requirements for the installation of overvoltage protection devices are set in European Normative EN 60079-25. For the U.S., Canada refer to ANSI/ISA RP12.6.01, NEC and CEC.

The manufacturing date of each EE300Ex is shown on the hazardous product label, at the bottom right corner, as follows:

WWYYYY

WW .........week of the year

YYYY ........ year

3.2 Enclosure

The EE300Ex features has a modular design and consists of:

• Bottom section with the connection and grounding terminals

• Front section with the electronics and the probe

167 (6.6“)

70 (2.8“)

4.5 (0.18“)

8.4 (0.33“)

When the front section has been removed from the hazard area, e.g. for calibration, the empty bottom section shall be protected against dirt and electrostatic charge with the blind front cover HA011401 (see accessories).

Unused cable glands shall be closed with appropriate sealing plugs (see accessories).

To mount the bottom section use 4 screws diameter < 4.5 mm

(0.18“)

3.3 Assembly in category 1 (Zone 0 / 20); Division 1

Only intrinsically safe power supply devices are approved to supply EE300Ex in category 1 or Division 1.

In areas belonging to gas group IIC or Class I, Division 1, Group A, B, it must be ensured that during installation and operation, the possibility of impact and friction sparks has been excluded in rarely occurring fault situations.

Work on open sensor must only be performed if it is guaranteed that no explosive atmosphere is present.

In category 1 or Division 1, the sensor line should be laid in an earthed metallic protective hose. With Group III or Class II, III, ensure that there are no dust or fibers and flyings deposits in the protective tube.

CH1 and CH2 must be galvanically isolated from one another during operation.

There is no display permitted in the gas hazard area EPL Ga for Group IIC or Class I, Division 1, group A, B and in the dust hazard area for groups IIIA, IIIB and IIIC or Class II, III.

The probe for wall mount is not permitted to be used for Zone or Division bushing.

User Manual EE300Ex Humidity / Temperature Sensor

3.5 Probe mounting

The probe of the EE300EX sensor shall be located at the most representative location for the RH and T of the process to be monitored.

For accurate measurement it is of paramount importance to avoid temperature gradients along the probe.

Whenever possible, install the entire probe inside the environment to monitor. If the probe is installed into a wall, than isolate thermally the backend of the probe looking out of the wall.

The probe shall be mounted horizontally or vertically, with the tip of the probe pointing downwards.

In applications where condensation is likely to happen:

• The cable shall form a drip loop close to the probe.

• Use the drip water protection (see datasheet accessories, code HA010503) for vertically mounted probe.

Ensure appropriate mechanical stability and sealing of the probe mounting taking into account specific influences at the site, such as vibrations, shocks or temperature changes.

The probe and the cabling shall be handled and installed to avoid electrostatic charges. (e.g. metal hose)

Filter caps

The following filter caps offer good protection against electrostatic discharge for explosion group IIB, but are not permitted for use in EPL Ga IIC or Class I, Division 1, Group A, B:

• Membrane filter (order code F2)

• PTFE filter(order code F5)

• Membrane on stainless steel body (order code F10)

• PTFE on stainless steel body (order code F11)

• H2O2 filter (order code F12)
