2 OPERAING PRINCIPLE High n Low pressures re seprte y sensor ssemly onsisting of mgnet, piston, eflon sel n rnge spring. he ifferene in pressure uses the sensor ssemly to move in proportion to the nge ginst rnge spring. 0 DPG REED SWICH RANGE SPRING A rotry mgnet, lote in seprte oy vity n isolte from the ting pressures, is rotte y mgneti oupling s per the liner movement of the sensor ssemly. A pointer tte to the rotry mgnet inites ifferentil pressure on the il. Swit : Ree swites re lote jent to the pressure mer n re tivte y the mgneti fiel of the sensor ssemly. HIGH PISON MAGNE ELON SEAL ROARY MAGNE POINER LOW PISON ECHNICAL DAA (MODEL 0 DPG) Rnges : to 0-10 r Units of lirtion : 2 Kg/m, kp, r, mr, psi.
