In addition to the differential pressure PS 18 differential pressure sensor records a positive and negative pressure. Central Unit is beryllium bronze, in accordance with the differential pressure between the displacement of the two chambers of the diaphragm spring pressure cells. Measurement of displacement without contact, through an inductive displacement recorder. Against each other or the device does not contain any components, mechanical wear and cleaning of components. This simple and accurate measurement of the transmitter is particularly suitable for applications in air conditioning and ventilation technology. Technical data: high sensitivity, excellent long-term stability and low drift of zero and hysteresis measurement range: 0 100,000 PA-the PA 0-250 from linear, usually output signal ± 2.5%: 0-10 V,0-20 mA,4-20 mA power supply voltage: 24 v, 24 VDC, 230 Vac media: air all non-corrosive gas request for further information.另外:我公司還代理此品牌的如下型號(hào):PUC24，P82R，P26，PK15，PS27，REG21，RMA200，KAL84，廣告/SA1000 BA90。
