Transmitter
RZ23T Series Pressure Transmitter
Product Details
RZ23T series pressure transmitters use imported ceramic capacitor sensor, no filled liquid, no contamination for processing, solid ceramic diaphragm, excellent anti-corrosion and anti-abrasion performance. When overloaded, the diaphragm can avoid being by sticking to the bottom of ceramic lining. When pressure goes back to normal, the performance of the transmitter goes back to normal too because of its strong ability of anti-overload and anti-impact, micro-integration structure that integrates sensor and flexible circuit inside a stainless shell. Signal processing uses imported conditioning circuit that has high-stability, high-efficiency, better linearity (<0.01%). All products experienced strict test and burn-in screening:
l Reversed polarity and transient overcurrent/overvoltage protection, in accordance with EMI protection requirements.
l Accurate zero-point/range calibration via outer calibrator.
l Multi-specification signal for output connection: 4-20mA, 0-5V, 0.5-4.5V, etc.
l Wide range of measurement.
l Stainless steel structure.
l Mutli-type of pressure connection.
l Protection level: IP65.
l Explosion-proof product, acquired explosion-proof certificate with indication Ex ia II C T6.
RZ23T integrates superior sensor element, excellent electrical circuit and advanced packaging technology all in one. It’s the ideal pressure measurement product in mechanical and hydraulic area using.
Classical applications:
u Automobile brake system, lubrication oil pressure measurement.
u Hydraulic/pneumatic equipment: air compressor, injection molding machine, automobile lubrication oil, etc.
u Pressure measuring for central air-conditioner, auto air-conditioner, etc.
