Dew Point Sensor -80 to +20 oCtd & -20 to +50 oCtd
The new generation of CS Instruments dew point sensors FA510 / 515 come with 2 and 3 wires technology, it can be providing 4…20mA and RS 485 (Modbus-RTU) both output signal at the same time and enables a reliable and long-term stable monitoring of the dew point in industrial application.
With a digital RS 485 interface, all values like e.g. dew point, temperature, absolute humidity... which are measured and calculated by the dew point sensor can be retrieved via the Modbus protocol. The sensor included sinter cap protects the sensor tip from dust and other particles, this ensures a stable measurement and low maintenance.
