The universal transmitters for temperature measurement with resistance thermometers and thermocouples – in a 6-mm housing with infrared interface and SIL approval.
The universal ThermoTrans P 32100 temperature transmitters provide connection possibilities for all common thermocouples and resistance thermometers. They can be flexibly adapted to the respective measuring task using DIP and rotary encoder switches or via an IrDA port.
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 P 32100 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. All standard 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 switches are used, for example, when manipulations or mix-ups must be precluded.
For applications requiring a high level of functional safety, Knick offers the ThermoTrans P 32100 transmitter with SIL approval. The requirements of EN 61508 were implemented through specially developed hardware and software. The fail-safe concept makes use of structural measures at the device level (redundancy of system components) and diagnostic methods for selective fault detection. The product is SIL 2 approved (EN 61508) by an authorized body (TÜV Rheinland). SIL 3 in redundant implementations.
