Pressure Transmitter Dealers in Bikaner

• Brand Name: Fischer
• Model Number: DE23

Working Principle: -DE23 is based on capacitance sensor element and can measure positive gauge, negative gauge or differential pressure. The pressure is measured directly by a micro-machined silicon-on-glass differential capacitance sensor element. Pressure changes cause capacitance changes interpreted by the integrated electronics. Key Features: 1.Very low pressure measurable without long-term drift 2.Rugged design 3.Maintenance free 4.Over-pressure protected Key Specifications: 1.Measuring range: 0 ~ 25 Pa to 0 ~ 1000 Pa 2.Maximum static operating pressure: 1.0 bar 3.Maximum safe pressure: 1.7 bar 4.Straight line error (max.): 1.0 % Full scale 5.Pressure connection: screw clamp connectors (aluminum) for 64 mm or 86 tube 6.Repeatability: 0.1 % full scale 7.Operating ambient & media temperature: -10° C to +70° C 8.Protection class: IP65 per DIN EN 60529 9.Linearity: < 2% Full scale 10.Electrical output: 4-20mA linear, 2 – wire 11.Power supply: 24 V DC 12.Material, housing: Polyamide PA 6,6 13.Materials, media contact: Silicon, PVC, aluminum, brass Application areas: 1.Filter status condition monitoring 2.Precision air duct measurement 3.Clean room pressure balance monitoring 4.Burner air feed low pressure detection 5.Oven air feed control

Fischer ME50 is programmable pressure transmitter for liquid and gaseous media. It is equipped with: Ceramic membrane / diaphragm measuring cell for measuring range upto 400 mbar Front-flush piezoresistive element based measuring cell for measuring range above 400 mbarME50 can be configured or programmed to suit onsite conditions and media via either onboard display keypad or tool adaptor EU13. Working Principle: For ceramic diaphragm measuring cell (< 400 mbar): The measuring pressure is directly applied on the rugged ceramic diaphragm. This applied pressure cause distortion on measuring membrane. The change in capacitance due to pressure, is measured at the electrodes of the ceramic carrier and diaphragm.The electronics in the pressure transmitter housing convert the change in capacitance into standard electrical signals. For piezoresistive diaphragm measuring cell (≥ 400 mbar): The measured pressure acts on silicon diaphragm of a semi-conductor chip, causing it to distort. The specific resistance of the material changes in proportion of the level of distortion. The electronics module in the pressure transmitter convert the change in resistance into standard electrical signals.   To optimise performance in line with prevailing process conditions, it is also possible to configure the pressure transmitter on-site via PC based programming adaptor EU13.
