All-in-One Universal Transmitter with Automatic Force, Strain, Position and Temperature Sensor Recognition


Knick USA announced the North American market introduction of its PolyTrans P 32000 universal sensor transmitters, an easy-to-operate, high-reliability universal sensor transmitter, offering added functionality within a single, cost-effective, user-friendly unit.

Measurements of temperature, strain, force and position are common within vir¬tually all market sectors.

This is especially true within control and monitoring and safety shutdown systems. As a result, today’s commercial sensing technologies are available in a variety of electrical formats, connector types, ranges, materials, supply voltages and output signals. Multiple sensor types may also be specified for the support of a single application.

A sensor transmitter is used to process raw output signals; linearize them, if required; and then standardize them for further processing. As accuracy, flexibility, functional safety, and electrical safety are all essential, multiple sensor types have historically called for the use of multiple transmitter types. Or, certain multi-sensor transmitters have traditionally offered some added functionality, though typically at much higher costs and with reduced ease of use.

To solve this market challenge, Knick USA has developed PolyTrans P 32000 universal sensor transmitters. The easy-to-operate transmitters can automatically recognize the signal outputs of any 2-, 3- and 4-wire temperature, force and strain sensors, resistors, potentiometers, resistive sensors, and similar sensing technologies. They can also recognize standard thermocouple signals, with either internal or external reference junction compensation, and without the need for further adjustments.

The compact design of the PolyTrans P 32000 also facilitates its ease of installation within space constrained environments.

Knick PolyTrans P 32000 “all in one” universal transmitters may also be flexibly adapted to individual measurement tasks using DIP and rotary encoder switches or an IrDA interface. A broad ranged power supply covers all common voltages from 24 to 230 V and ensures maximum safety, even when operating with unstable power grids. Three-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 measurement signal transmission. Units are also available with SIL 2 approvals (per IEC 61508) to meet more stringent functional safety requirements. All P32000 units are also accompanied a comprehensive five-year product line warranty.
