Description
The analogue temperature transmitters of the T91 family are geared to the special requirements of industrial applications. Depending on their output signal they are ideally suited for direct connection to processors such as PLCs or PC-A/D converters with voltage or current inputs. The transmitters convert the temperature-dependent change in resistance (for resistance thermometers) or the temperature-dependent change in voltage (for thermocouples) into a 0 ... 10 V or 4 ... 20 mA output signal. These
standard signals allow an easy and reliable transmission of temperature measurement values.
These temperature transmitters are characterised by fixed measuring ranges configured according to customer specifications, combined with zero and span potentiometers, which enable the fine adjustment of small corrections on site. Industry-compliant accuracy, interference resistance and sensor monitoring are further features of these compact signal converters. The T91.10 head mounting transmitters can be mounted inside any DIN Form B connection head. In addition the T91.20 head mounting version is also suitable for Form J connection heads.
