Description

The flexible ThermoTrans A 20210 temperature transmitters provide connection possibilities for most of the common thermocouples and resistance thermometers. They can be flexibly adapted to the respective measuring task by the user using DIP and rotary encoder switches. 3-port isolation with protective separation up to 300 V AC/DC according to EN 61140 ensures optimal protection of personnel and equipment as well as unaltered transmission of the measurement signals. The ThermoTrans A 20210 offer maximum performance in the smallest of spaces.
Resistance thermometers can be operated in 2-, 3-, or 4-wire configuration. The connection configuration is automatically recognized, adjustment is not required. Thermocouples can be read with internal or external reference junction compensation.
Input voltage signals up to +/- 1000 mV are converted into 0/4 to 20 mA or 0 to 10 V standard signals. This enables low-cost implementation of current measurements using shunt resistors, for example.
Special measuring tasks can be solved with ThermoTrans devices which Knick configures according to individual specifications.
Fixed-range devices without switch are used, for example, when manipulations or mix-ups must be precluded.
