PT-406 Pressure Transmitter | High-Precision Pressure Sensor for Refrigeration & HVAC/R

Product Overview：

1，The PT-406 Pressure Transmitter is a high-performance pressure sensor specifically engineered for the refrigeration and HVAC/R industries. Powered by an internationally renowned piezoresistive piezoresistive sensor core and advanced signal conditioning ICs, the PT-406 provides precise digital temperature compensation and non-linear correction, delivering reliable analog outputs (4–20mA, 0–5VDC).

2，To tackle the common challenge of moisture in cooling environments, the PT-406 features an exclusive anti-condensation design. This structure prevents water vapor from condensing inside the sensor cavity, protecting the circuit board and dramatically extending operational lifespan. With superior stability, high sensitivity, and exceptional cost-effectiveness, the PT-406 is the ideal choice for air conditioning systems, chillers, and commercial refrigeration units.
