Standard transmitters for temperature measurement with resistance thermometers and thermocouples - in a 6-mm housing.
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 using DIP and rotary decoding switches. 3-port isolation with protective separation up to 300 V AC/DC according to EN 61140 ensures optimum protection of personnel and equipment as well as unaltered transmission of measuring signals. The ThermoTrans® A 20210 offer maximum performance in the smallest of spaces.
Resistance thermometers can be operated either in 2-, 3-, or 4-wire configuration. The configuration type is automatically recognized, adjustment is not required. Thermocouples can be detected 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.
The devices meet the requirements of type of protection "n". This means they can be installed and used in Zone 2 hazardous areas in the EC, the USA, and in Canada. Thanks to their approval to Class 1, Division 2 (UL 1604), they can also be used according to the traditional North American classification system.
Special measuring tasks can be solved with ThermoTrans® devices that Knick configures according to individual specifications. Fixed range models without switch are used, for example, when manipulations or mix-up are to be excluded.
