• Process temperature, process pressure

The use of special materials means that the sensor is suitable for exposure to continuous

temperatures of up to 125 °C (257 °F). It may be exposed to temperatures of up to 150 °C (300 °F)

for a short time (max. 60 minutes) for sterilization phases. The sensor's pressure-resistance is 12

bar (174 psi), abs at temperatures up to 90 °C (194 °F) and at higher temperatures is always above

the steam pressure. The sensor is suitable for underpressure applications.

• Temperature measurement

The sensor has an integrated temperature sensor with a temperature response time t90 of less

than 26 s, making efficient phase separations possible at varying and quickly changing process

temperatures. The temperature sensor is embedded into the PEEK body without any seals, thereby

ensuring a long sensor service life.

• Temperature compensation

The following types of temperature compensation are available in the Smartec CLD134:

– Linear compensation with user-configurable temperature coefficient α

– Compensation according to IEC 60746-3 for NaCl

– Compensation according to user-programmable coefficient table with a maximum of 10

elements.

• Concentration Measurement

The transmitter can be switched from the conductivity operating mode to the concentration mode.

In the concentration mode, four user-programmable and various pre-programmed concentration

curves are available, especially for common CIP solutions. In this way, it is possible to display the

concentration directly as a %.

• Remote parameter set configuration

Smartec CLD134 can be ordered with remote parameter set configuration (measuring range

switching, MRS) in order to:

– Cover a large measuring range.

– Adjust temperature compensation when the product is changed.

– Switch between concentration curves.

• Device versions

The Smartec CLD134 measuring system is available as both a compact version for simple

installation and as a remote version (the sensor and transmitter are connected by a cable).

Furthermore, the transmitter can be ordered separately without a sensor.

Measuring system

A complete measuring system comprises:

• The remote version of the Smartec CLD134 transmitter

• The CLS54 conductivity sensor with an integrated temperature sensor and fixed cable

or

• The compact version with the integrated CLS54 conductivity sensor

Optionally for the remote version: CLK6 extension cable, VBM junction box, mounting kit for post

mounting
