The universal transmitters for temperature measurement with resistance thermometers and thermocouples - in a 6-mm housing with infrared interface, SIL approval and broad-range power supply.

The ThermoTrans® P 32100 universal temperature transmitters provide connection possibilities all common thermocouples and resistance thermometers. They can be flexibly adapted to the respective measuring task using DIP and rotary decoding switches or via an IrDA® interface. The broad-range power supply covers all common supply voltages from 24 to 230 V and ensures maximum safety even with instable mains supplies. 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® P 32100 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. All commercial 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.

Knick offers the ThermoTrans® P 32100 transmitter with SIL approval for applications with high demands on functional safety. The requirements of EN 61508 were implemented by a specially developed hardware and software. The fail-safe concept makes use of structural measures at the device level (redundancy of system components) and diagnostics methods for selective fault detection. The product is SIL 2 approved (EN 61508) by an authorized body (TÜV Rheinland).
