The MPS™ platform is hardened to harsh environmental conditions including rapid transients that deliver the best performance with a very low false positive rate. With its extremely fast response time, the accurate sensor output is delivered in seconds. The sensor is immune to poisons and with built-in self-test functions, you are assured the MPS™ sensor is working within specification. The MPS™ comes in two different packaging options. The S4 is hardened for commercial ATEX certified applications, and the cost-effective Mini targets residential applications. Both packages meet the exact same performance standards and can be calibrated for any of the refrigerants listed below.

MPS™ Refrigerant Gas Sensor User Manual:

How the MPS™ Flammable Gas Sensor Works

MPS™ Refrigerant Gas Sensors are smart sensors with built-in environmental compensation that detect and accurately quantify low-global-warming (LGW), flammable (A2L), and non-flammable (A1) refrigerants used in HVAC applications. They are robust, extremely poison resistant, and come factory calibrated. Sensor readings are output on a Universal Asynchronous Receiver and Transmitter (UART) digital bus or industry-standard analog output. Each type of refrigerant sensor is designed and calibrated to detect a single, specific refrigerant gas (e.g. R-32).
The MPS™ transducer is a micro-machined membrane with an embedded Joule heater and resistance thermometer. The MEMS transducer is mounted on a PCB and packaged inside a filtered enclosure that is permeable to ambient air. Presence of a refrigerant gas causes changes in the thermodynamic properties of the air/gas mixture; these properties are measured by the transducer and processed by patent-pending algorithms to report an accurate concentration.

Communicating with an MPS™ Refrigerant Gas Sensor

This section describes the software interface requirements for MPS™ Refrigerant Gas Sensors and is useful to system integrators when designing a sensor assembly into a final product. The preferred method of communicating with the sensor is over the serial interface using the UART (Universal Asynchronous Receiver/Transmitter) protocol. Section 2.1 provides the necessary information for communicating using UART. Section 2.2 provides information for measuring sensor output via the analog voltage output pin.
