T91 ANALOGUE TEMPERATURE TRANSMITTER

The analogue temperature transmitters of the T91 model series are matched to the specific requirements of industry. Depending on the output signal, they are particularly suitable for direct connection to evaluation instruments with voltage or current inputs such as PLC's or AD conversion cards in PC's.

The temperature transmitters convert the temperaturedependent change in resistance of resistance thermometers or the temperature-dependent voltage change in thermocouples into a 0 ... 10 V or 4 ... 20 mA output signal. With these standardised signals, the measured temperature values can be transmitted simply and safely.

The temperature transmitters of the T91 model series are fixed-range transmitters which are supplied with the required measuring ranges in line with the customer's requirements. A later fine adjustment of the zero point and the span can be made with potentiometers once fitted.

The T91.10 head-mounted transmitters can be located in any form B DIN connection head, while the T91.20 head-mounted transmitters also use form J connection heads.
