PCE Instruments PCE-P18 Modbus RTU Compact temperature and humidity sensor with RS-485 output, Modbus RTU interface, wall mount, IP65 protection for HVAC environmental monitoring
(Incl. Tax: €177.39)
Temperature and relative humidity sensor designed for HVAC applications, featuring an RS-485 interface with Modbus RTU protocol for continuous environmental monitoring. The model PCE-P18-0A0E0 accurately detects parameters through a semiconductor element and transmits the measured values as a normalized signal. The output occurs via a two-wire line and connections with screw terminals in a water-resistant IP65 housing. Compact dimensions and provision for wall mounting make the sensor ideal for multiple installations, even with different filters.
