Digital Differential Pressure Transmitter with Double Sensors Dp Sensor Ce (PCM639)

PCM639 Differential Pressure Transmitter with double sensorsOverview PCM639 Differential Pressure Transmitter is based on 2 absolute pressure sensors, which can be used where differential pressure is more than 10% of the maximum pressure range. Because of the use of unconventional method of measuring differential pressure with 2 absolute pressure sensors, PCM639 has completely different advantages from traditional differential pressure measuring elements.CM639 Differential Pressure Transmitter does not measure differential pressure directly but use 2 absolute pressure sensors to make indirect measurements. While reducing costs, this pressure transmitter also performs well under the circumstance of overpressure on one side. The differential pressure range should not be less than 10% of the maximum pressure range. There are 2 pressure ports on each side, so the product can be easily installed on pressure pipelines. Therefore, the differential pressure value can be accurately measured even in the case of a high ratio of pressure range divided by differential pressure. PCM639 also adopts the microprocessor-based MSP430X, which enables digital error compensation to eliminate all repeatability errors (such as linearity and resistance dependence), and the sensor signal is measured by a 16-bit AID converter, so in the whole pressure range, each standard pressure range can gain 0.1% measurement accuracy.ApplicationsHydropowerChemical industryUrban water supplyScientific researchAccurate measurement of differential pressure of fluid  Electrical performance parameters Pressure range0~100MPaPressure referenceAbsolute pressureSupply12~30V, 24V recommendedOutput 4~20mAOperating temp.-25ºC~80ºCStorage temp.-40ºC~100ºCResponse time≤1ms (up to 90%FS)Insulation resistance100MΩ/500VDCProtectionIP65    Structural performance parameters Housing material304Medium compatibilityAll kinds of liquids and gases compatible with stainless steel  Basic parameters Measurement error±0.5%  Structure & dimension   Dimension(In mm)  Pressure range selection CodeW10kW35kW100kW250kW600kW1MW2.5MW6MW16MW40MStatic pressure20kPa70kPa200kPa500kPa1.2MPa2MPa5MPa12MPa32MPa80MPaDifferential pressure ≥2kPa7kPa20kPa50kPa0.12MPa0.2MPa0.5MPa1.2MPa3.2MPa8MPa  How to order Example: PCM639-W10kC2X1Product model is PCM639, static pressure is 20kPa, differential pressure is greater than 2kPa, threaded connection is G1/4, and test report is provided.Ordering tips:1 Please pay attention to the compatibility between measuring medium and product contacting part.2 For special requirements on shape and performance parameters of the product, customization is available.About Us:Certifications:FAQ:1.    Q: Are you manufacturer or trading company?         A: We are manufacturer which focuses on pressure sensor for 33 years. 2.    Q: What international certificates do you have?         A: ISO9001, CE, RoHS Certificated. 3.    Q: What is your production capacity?         A: We produced 1500000 pieces pressure sensor in year 2017. 4.    Q: What is the lead time of your product?         A: Stocks are available for some products.
