Symaro™ Duct Temperature Sensor Modbus RTU QAM2151.
Use The duct temperature sensor is used in ventilation and air conditioning plants as: ● Supply or exhaust air temperature sensors ● Limit sensors, for example, for minimum limitation of the supply air temperature ● Reference sensors, for example, for compensation of the room temperature as a function of the outside temperature ● Dew point temperature sensors ● Measuring sensors, for example, for measured value indication or for connection to a building automation and control system Technical design Cable e
● ● For exhaust air temperature control: Always upstream of the exhaust air fan As a limit sensor for the supply air temperature: As close as possible to the air outlet into the room ● For dew point control: Immediately after the spray trap of the air washer Manually bend the probe so that it lies diagonally across the duct or in equally spaced windings across the entire duct cross-section. The probe must not touch the duct wall. Mounting instructions Mounting instructions are enclosed in the package.
