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).

Humidity and Temperature Sensor | 14

The stainless steel mounting flange is not appropriate for pressure-tight mounting. For pressure-tight
requirements, use EE310-T10.

For probe hanging on its cable from the ceiling in applications where condensation is likely to happen, it is
important to avoid condense water getting from the cable to the probe and into the sensing head. For this
purpose, use the drip water protection (see 8 Spare Parts and Accessories).

4.5 Mounting Pressure-Tight Probe of EE310-T10

WARNING

General safety instructions for pressure-tight 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.

The probe is rated with leakage rate B according to EN12266-1.

User Manual EE310

4.5.1. Installation of the Probe Directly in the Process

NOTICE

For direct probe installation shut-off valves shall be placed on both sides of the probe insert (see Fig. 10
Installation of the EE310-T10 probe directly into the process). 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. 10) by a new one every time before re-installing the probe.

Probe installation steps

1. Close both shut-off valves.

2. Place the sensor probe into the probe insert and adjust the immersion depth.

3. Tighten the lock nut with a torque of 30 Nm.

4. Open the shut-off valves.

WARNING

Strictly observe the tightening torque. A torque lower than 30 Nm results in a smaller retention force of the
clamping sleeve. This leads the risk of sudden expulsion of the sensing probe due to the pressure. A torque
higher than 30 Nm may lead to permanent deformation of the clamping sleeve and the sensing probe. This
would make the removal and re-installation of the probe difficult or even impossible.

4.5.2. Installation of the Probe with Ball Valve Set

User Manual EE310

The ball valve set allows for installation and removal of the probe without process interruption.
For mounting into a duct, the ball valve shall be installed perpendicular to the flow direction.

NOTICE

The two metal sealing rings (see Fig. 11 Installation of the probe by utilizing the ball valve set) shall be
replaced every time prior to re-installing the probe.

The temperature during probe installation may deviate by max. ±40 °C (±72 °F) from the regular temperature
during normal operation.

Installation of the probe (see Fig. 11)

1. Install the probe into the ball valve while the ball valve is closed.

2. Open the ball valve.

3. Slide the probe through the ball valve to the desired immersion depth. Depending on the process pressure

additional tools may be necessary for pushing the probe into the process. Make sure not to damage the probe
and the cable.

4. Tighten the lock nut with a torque of 30 Nm.

WARNING

Observe strictly the tightening torque. A torque lower than 30 Nm results a smaller retention force of the
clamping sleeve. This leads the risk of sudden expulsion of the sensing probe due to the pressure. A torque
higher than 30 Nm may lead to permanent deformation of the clamping sleeve and the sensing probe. This
would make the removal and re-installation of the probe difficult or even impossible.

2. Slowly loosen the lock nut with a spanner (spanner width 24) only till the probe is pushed out by the

overpressure in the process. Do not completely loosen the lock nut, but only as much as necessary for the
probe to slide.

3. After the probe has been pushed out of the process up to the stop, close the ball valve.

4. Remove the probe from the ball valve.

NOTICE

Observe the correct positioning of the sealing element 1 before reinstalling the probe.

Description Order Code

Ethernet module for remote probe type T5 and T10 HA010606

Ethernet module for duct mount type T2 HA010607

Tab. 16 Accessories order code

Due to strong self-heating effects, the Ethernet interface is only recommended with the types T2, T5 and T10
(duct mount and remote probe). Wall mount applications with Ethernet interface shall be realized with type T5 and
2 m probe cable by fixing the probe onto the wall with the wall mounting clip HA010211.

5.7 Pluggable Probe (Option PC4)

EE310-T5 and EE310-T10 sensors are optionally available with pluggable sensing probe, which is attached to
the EE310 enclosure by a push-pull plug. If the probe or the probe cable gets damaged it is possible to easily
replace the probe without humidity and temperature adjustment. The replacement probe (see 8 Spare Parts and
Accessories) is supplied with a set of 7 individual parameters.
