Operating instructions for EE310 Humidity / Temperature Transmitter
3.3.4 T10: Pressure tight probe up to 20 bar
(300 psi)
EE310-T10 are transmitters with pressure tight remote probe.
Process pressure range 0.01...20 bar
(0.15...300 psi)

T working range probe:
-40...+180 °C
(-40...356 °F)
electronics:
-40...+60 °C
(-40...140 °F)
-20...+50 °C
(-4...122 °F)
(with display)
The probe shall be mounted horizontally or vertically pointing downwards.
For accurate measurement it is of paramount importance to avoid T gradients along the probe. In
case of large T difference between the front and the back of the probe, it is highly recommended
to insert the probe completely into the process. Should this not be possible, place a thermal
isolation layer on the part of the probe outside the process (on the cable side).

General safety instructions for installation
The installation, commissioning and operation of the EE310-T10 may be performed by qualified
staff only. Special attention shall be paid to the correct installation of the probe into the process.
In case of inappropriate installation there is the risk for the probe to be suddenly expulsed due to
the pressure in the process.
Bending over the sensing probe should be avoided under any circumstances!
Make sure that the surface of the probe is not damaged during installation. A damaged probe
surface may lead to damaged seals and consequently to leakage and pressure loss.
Installation of the probe directly in the process
(see
Fig. 12 Installation of the EE310-T10
probe directly into the process)
For direct probe installation into a duct stop valves shall be provided on both sides of the probe
insert. This allows the sensor probe to be easily removed for maintenance and calibration.
For direct installation into a pressure chamber make sure that the pressure in the chamber
and the ambient pressure are equal before removing the probe. The temperature during probe
installation may deviate by max. ±40 °C
(±72 °F)
from the regular temperature during normal
operation.
Replace the metal sealing ring (see
Fig. 12 Installation of the EE310-T10 probe directly into the
process
) by a new one every time before re-installing the probe.
Probe installation steps
•
Close both valves.
•
Place the sensor probe into the probe insert and adjust the immersion depth.
•
Tighten the lock nut with a torque of 30 Nm.
•
Open the valves.
