Temperature compensation

In addition, a Pt 100 temperature sensor is integrated in the inner electrode. The high thermal

conductivity of the sensor means that the temperature adjusts quickly to the fluid temperature. This

enables precise temperature compensation using the connected transmitter.

Robustness

The sensor is characterized by excellent thermal, chemical and mechanical resistance properties.

Use in superheated steam and ultrapure water

Special materials are available for these applications. A nominal operating life cannot be indicated

for the EPDM standard material in these cases.

A VMB junction box and another CYK71 cable are required for the cable extension.

Mounting

Installation instructions

1. Mount the sensor directly on a process connection that matches the version or alternatively

install it in a CLA751 flow assembly.

2. Ensure that the electrodes are fully immersed in the medium during measurement.

 The insertion depth must be at least 50 mm (1.97 in).
