Key technical specification

Table: Key technical specification for the Ambient Monitor E1/S1

 

Note 1: Sensor is designed to measure in the range 0 to 20000 ppm with specified in the table accuracy.
Note 2: Sensor provides readings in the extended range but the accuracy is degraded compared to specified in the table one.

Note 3: Normal operating range: 0-80%RH, beyond this limit sensor may read a reversible offset with slow kinetics (+3%RH after 60h at humidity >80%RH).

Note 4: In safety relevant applications it is strongly recommended to check the sensor every month

 

Communication interface

For the communication to other devices (PLC) RS485 with MODBUS RTU is used. Modbus is a simple, open protocol for both PLC and sensors. Details on Modbus can be found on www.modbus.org.
