Analog pressure gauge D4

differentialthreadedstainless steel

Measurement of extremely small differential pressures Robust design Direct indication of the differential pressure Many customised versions available Application For differential pressure measurement of non-corrosive, gaseous, dry media. Especially suitable for filter loss measurement in air conditioning and ventilation applications. For measuring gas or vapour, observe the table "Selection Criteria as per EN 837-2" (see appendix)! Technical data Function The "plus" pressure (= high pressure) is applied to the inside of the diaphragm. The "minus" pressure (= low pressure) is applied to the inside of the pressure-tight housing. The pressure difference causes the diaphragm to change its shape, thus generating the movement required to measure the pressure. This displacement is picked up by the movement. The differential pressure is directly indicated by a pointer. Ranges (EN 837-3/5) See ordering table Application area Static load: Full scale value Dynamic load: 0.9 x full scale value Overpressure safety Full scale value Temperature performance Indication error when the temperature of the measuring system deviates from the normal temperature of 20 °C: at rising temperature approx. ± 0.6 %/10 K falling temperature approx. ± 0.6 %/10 K of full scale value Standard design Measuring element (wetted part) Capsule element, CuBe alloy Zero correction From the front Seal (wetted part) NBR (Perbunan) Options Back flange 3-hole fixing, panel mounting bezel Hose connections Special scales Other process connections
