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).
