The FIS5000 serie represents a new compact modules line for detecting refrigerants that has negative impact on global warming (*)

The FIS5084 module can easily be installed into any HVAC and refrigerating equipment. The embedded circuit contains the SB type semiconductor gas sensor (SB43A-00). Since the module is pre-calibrated at the factory, users do not need expensive and complicated calibration equipment and procedure.

Main Features

• Factory pre-calibrated and high reliable module
• Designed to comply to JRA 4068:2016R, IEC60335-2-40 Ed6.0 and RoHS2
• Easy maintenance with designed life of about 10 years
• Supply voltage: 5Vdc
• Output signal: open collector type (alarm set @5000ppm R32)
• Concentration output: UART communication (available as option) - Modbus (available soon)
• Warm up time: ∼7seconds
• Current consumption: 40mA (initial peak of 80mA)

The module is available in two configurations:

• FIS5084-01NC - Module without case
• FIS5084-01C1 - Module with case

(*) Refrigerants are a gas heat-transfer medium for lowering temperatures. This gas is a critical part of temperature control equipment used in air conditioners, freezers, refrigerators, and other equipment. At the same time, chlorofluorocarbon gas used as a refrigerant is known as a greenhouse gas that has a negative impact on global warming. Society demands reduced emissions of substances that impact climate change for the worse. In the 1980s, scientists began suspecting that HCFCs, then used as a main refrigerant source, contributed to destruction of the ozone layer. The Montreal Protocol, signed in 1987, called for eliminating all HCFCs by the year 2020. Today, HFCs are used as the main source of refrigerants. These chemicals have no impact on the ozone layer; however, when released into the atmosphere, they cause a greenhouse effect that impacts global warming. Beginning in 2019, HFCs have joined the list of regulated chemicals subject to mandatory emissions restrictions. The Nissha gas sensor module for refrigerant detection will play an important role in detecting refrigerant leaks, reduction emissions, and solving this important social issue.
