IP65 10PSI Low Differential Pressure Transducer Die Cast Aluminum

PPM-WCY68-P500A Very Low Differential Pressure Transducer

 

Product Introduction:

pressure transducers sense gauge(static) or differential pressure and convert this pressure difference to a proportional current or voltage output. The 268 series is offered with a high level analog 0 to 5 VDC, 0 to 10 VDC or 4-20mA output. The 268MR offers multi-range capability and field configurable output. The Model 268 is packaged in a die-cast aluminum enclosure that is specifically designed for IP65 service to withstand environmental effects. Used in Building Energy Management Systems, the 268 and 268MR pressure transducers are available for air pressure ranges as low as 0.1 in W.C. (25 Pa) full scale to 100 in. W.C. (25 kPa) full scale. Static accuracy is ±1% full scale in normal ambient temperature environments. The 268 series utilizes an improved all stainless steel micro-tig welded sensor, which is enclosed in a welded stainless steel body. The tensioned stainless steel diaphragm and insulated stainless steel electrode, positioned close to the diaphragm, form a variable capacitor. As the pressure increases or decreases, the capacitance changes. The change in capacitance is detected and converted to a linear DC electrical signal by Setra’s unique electronic circuit. The micro-tig welded tension sensor allows up to 10 psi overpressure(in either direction), with no damage to the unit.The improved sensor design also allows the Model 268MR version to have 6 field selectable pressure ranges (bi-directional and unidirectional) in one unit. The simple flip of a dip switch enables the user to easily field calibrate the unit with minimal effort. Explosion- proof units are approved for ia II CT4.
