Description
Surface contact temperature/ tube contact temperature measuring transducers
THERMASGARD® ALTM1 - Modbus - T3
Calibratable surface-contact temperature measuring transducer (compact variant)
THERMASGARD® ALTM 1 - Modbus - T3 with Modbus connection, in an impact-resistant
plastic housing with quick-locking screws, pipe feeder, incl. strap, optionally with/ without
display, measures temperature (–50...+150 °C). International system of units SI (default)
can be changed to imperial (via Modbus).
The pipe surface-contact sensor is used to detect the temperature on lines, pipes (e.g., cold and warm water) or on heating sections for heating control.
The pipe surface-contact sensor is used to detect the temperature on lines, pipes (e.g., cold and warm water) or on heating sections for heating control.
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.
