H2-CNI 0-10V-I

High-precision, maintenance-free hydrogen detection

H2-CNI 0-10V-I

High-precision, maintenance-free hydrogen detection

The H2-CNI 0-10V-I offers a 0-10V output signal and I2C connectivity for adjusting zero-point and gain of the sensor. Built on a catalytically active, siloxane-resistant element and operating on a non-isothermal calorimetric principle, this sensor delivers consistent performance from lab environments to real-world deployment.

Pin Configuration

Pin Configuration

Pin 1

+12V positive supply voltage with respect to ground


Pin 2

Sensor signal with respect to ground


Pin 3

Ground to the internal electronics. The pin is electrically not connected to the housing


SCL

Clock line of I2C bus, referenced to ground (pin 3)*


SDA

Data line of I2C bus, referenced to ground (pin 3)*



*The sensor can be operated without connecting the I2C bus. If connected, provide necessary pull-up resistors to SCL and SDA (e.g. 4.7 kOhm).
