Differential pressure switch for air handling units
Compact
Excellent long-term stability
Low-temperature use
Easy to mount
DTV is a lightweight, compact and robust differential pressure switch designed for supervising air handling units. It can be used in a variety of applications, including the monitoring of fans and filters, and controlling defrosting functions.
The differential pressure switch consists of sensor housing made of fibreglass-reinforced plastic with a synthetic membrane. The differential pressure affects the spring suspended membrane which is linked to a changeover contact.
DTV is designed for differential pressure up to 5000 pa and it can be safely and effectively used at temperatures down to -20°C.
The DTV differential pressure switch is easy to mount and provides excellent long-term stability.
The pressure that is connected to P1 is compared with the pressure connected to P2. When the differential pressure exceeds the setpoint value the contact changes. When the pressure switch is used to supervise a fan, one of the pressure connections can be left open.
