Description

Pendulum room temperature measuring transducer THERMASGARD® RPTM1 - Modbus - T3
Calibratable room pendulum temperature measuring transducer (with sleeve) THERMASGARD® RPTM 1 - Modbus - T3, with Modbus connection, in an impact-resistant plastic housing with quick-locking screws, cable sensor with stainless steel sleeve and plastic sinter filter (exchangeable), optionally with/ without display, measures temperature (–50...+150 °C). International system of units SI (default) can be changed to imperial (via Modbus).
Calibratable room pendulum temperature measuring transducer (with globe) THERMASGARD® RPTM 2 - Modbus - T3, with Modbus connection, in an impact-resistant plastic housing with quick-locking screws, cable sensor with a black plastic globe, optionally with/ without display, measures temperature (–50...+150 °C). International system of units SI (default) can be changed to imperial (via Modbus).

The pendulum sensor has been specially designed to detect the temperature in larger rooms or halls. The resistance thermometer achieves a very good representative measurement result due to its positioning in the room.
Innovative Modbus sensor with galvanically separated RS485 Modbus interface, selectable bus termination resistance, DIP switch for setting the bus parameters and bus address in current-free state, internal LEDs for telegram status display, two separate push-in terminals and large three-line display (illuminated, with customised programming in the 7-segment range and dot-matrix range). Uses internal diagnostics to detect sensor breakage or sensor short circuit as errors. The error messages can be retrieved via Modbus and are shown on the display. The sensor is factory-calibrated; an environmental precision adjustment by an expert is possible.
