PST offers a range of hydrocarbon infrared sensors that measure methane or propane gas over a range from 0-100% volume. The sensors are designed with non-dispersive infrared technology and respond to many hydrocarbon gases, including methane and propane.
The Standard series sensors provide a 'raw' signal output which require the user to provide their own drive electronics and software to derive the gas concentration, apply linearisation and temperature compensation. This can be achieved using the application notes on the downloads tab.
The sensors are available in Industrial Ex d IIC Certified, Mining M1 Certified, UL Approved, and Non-Certified versions.
The OEM-1 module is available for original equipment manufacturers who do not wish to develop their own electronics and software. The module has an inbuilt display and includes a 4-20mA output. The microcontroller contains all the necessary software and signal processing algorithms to enable the user to minimise the time-to-market.
