Description
CSPPM 14kPa Differential Pressure Transducer For Air Conditioning

PPM-WCY66-P500A Heating, Ventilating and Air Conditioning Differential Pressure Transducer

 

Product Introduction:

PPM-WCY66-P500A pressure transducers sense differential or gauge (static) pressure and converts this pressure difference to a proportional electrical output. The 266 is offered with a high level 0-10 VDC and 0 -5 VDC output or a 4-20 mA output.

Used in Building Energy Management Systems, these transducers are capable of measuring pressures and flows with the accuracy necessary for proper building pressurization and air flow control.

low pressure transducers are available for air pressure ranges as low as 0 to ±50 Pa full scale up to 5 kPa full scale. Static accuracy is ±1% full scale in normal ambient temperature environments. The units are temperature compensated to less than ±0.06% FS/°C (±0.033% FS/oF) of thermal error over the temperature range of -18 to +65 °C (0oF to +150oF). utilizes an all stainless steel micro- tig welded sensor. The tensioned stainless steel diaphragm and insulated stainless steel electrode, positioned close to the diaphragm, form a variable capacitor. Positive pressure moves the diaphragm toward the electrode, increasing the capacitance.

 

Applications :

Heating, Ventilating and Air Conditioning (HVAC)

Energy Management Systems

Variable Air Volume and Fan Control (VAV)
