Air DP Sensors & Switches Air DP switches for fan proving, single or multi-range air DP sensors for dirty filter monitoring and air flow or pressure control.
These highly accurate sensors are designed for differential pressure measurements of air and other neutral gases. The unit is especially suited for measurement and control in HVAC applications.See more
Sontay’s range of multi-configurable pressure sensors are designed for differential pressure measurements of air and other neutral gases. The unit is especially suited for measurement and control in HVAC applications.
The PA-65-x pressure transducers sense differential or gauge (static) pressure and convert this pressure difference to a proportional electrical output for either field selectable unidirectional or bidirectional pressure ranges. The PA-65-x series is offered with field selectable ranges and analog outputs of 0 to 5Vdc, 0 to 10Vdc, or 4 to 20mA. The measurement cell uses an advanced design capacitive element to ensure excellent linearity and stability.
Sontay’s range of field selectable multi-range differential pressure transmitters, incorporate a proven ceramic fulcrum lever technology for pressure measurement.
The PA-699 has three field selectable ranges in one unit, providing versatility for a multitude of applications.
These are highly sensitive air differential pressure switches, suitable for providing an indication of fan status and ‘dirty filter’ conditions. The switching setpoint is adjusted by means of a knob mounted under the main cover. Units are supplied complete with a duct fixing kit.See more
The PA-DPT differential pressure transmitter is ideal for measuring filter conditions, as well as many other applications in ventilation/air conditioning systems in buildings, laboratory's and clean rooms (air and non- corrosive gases). Featuring field-selectable output signals (3-wire 4-20mA, 0-10Vdc or 2-10Vdc) and 8 pressure ranges, unidirectional or bi-directional via jumpers. An optional LCD display is also available. Sensor types 01 & 02 have manual re-zero facility whereas the 01-HA version has an auto zero function for automatic zero point calibration making it a virtually maintenance free sensor.See more
