The PolyTrans P 32000 universal transmitters provide connection possibilities for all standard thermocouples, resistance ­thermometers, strain gauges, full bridges, resistors and potentiometers/resistive sensors. They can be flexibly adapted to the respective measuring task using DIP and rotary encoder switches or via an IrDA interface.

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 measurement signals.

The PolyTrans P 32000 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 commercial ­thermocouples can be read with internal or external ­reference junction compensation. To detect mechanical quantities such as force or strain, strain gauges can be connected in full-bridge configuration.

The ability to connect variable resistors and potentiometers creates a wide range of application possibilities, for example in the ­field of displacement or position detection. 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.

Knick offers the PolyTrans P 32000 transmitter with SIL approval for applications with high demands on functional safety. The requirements of EN 61508 were implemented through specially developed hardware and software. The implemented 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 SIL2 approved (EN 61508) by an authorized body (TÜV Rheinland). SIL3 in redundant implementations.
