Wind Pressure Switch

Introduction

A401 Model is a high performance negtive wind pressure switch pressure range from -2000~0Pa

A401 switches offer a wide switching differential and low set point tolerance over a broad operating temperature and set point range. They are manufactured in a automatic line to ensure the highest aua itv and accuracy. Theelass-flled polycarbonate housing contains a sensing diaphragm and an integral snap-acting switch. This design provides a high degree of stability and accommodates many sample line connector, terminal, and mounting options.

A401 switches are specially developed for air flow pressure systems. Such as in gas fired heating systems. Or ensuring ventilation in heat pumps or ensuring the exhaust air flow in pellet boilers and gas boilers. HVAC, Energy Management, Food Service, Comfort and Recreation, and Facility Management are a few of the industries served by this switches.
