42-1310 Low Pressure Sensor for Thermo King
The 42-1310 Pressure Sensor / Pressure Transducer is an aftermarket replacement for selected Thermo King transport refrigeration units. It monitors suction-side refrigerant pressure and sends pressure information to the refrigeration control system.
Product Description
The 42-1310 Pressure Sensor for Thermo King is designed for suction-side pressure monitoring in transport refrigeration systems. Thermo King parts catalogs describe it as a suction pressure transducer for selected SL, SLX, SLXe, SB and Spectrum refrigeration units.
The sensor converts refrigerant pressure changes into an electrical signal. The refrigeration controller uses this signal to monitor system pressure and manage refrigeration operation.
Part 42-1310 also appears as 421310. The commonly associated replacement or earlier number is 42-2284 / 422284. Other catalog references include 41-4403, 41-5251 and 41-7960.
Some current supplier listings specify a 200 PSIG pressure rating, 4-wire configuration, and 1/8″ NPT male thread for the 42-1310 transducer. Confirm the specifications and connector configuration against the original sensor before ordering.
