Brief Introduction
|
CYB4211 pressure transmitter which is developed specifically for water cooling units, compressors, air conditioning and refrigeration systems and other general measurement scenarios. It uses ceramic piezoresistive sensitive elements, corrected by digital circuitry and signal conditioning, to output standard signals for industrial applications and networking.
CYB4211 pressure transmitter are carefully designed with excellent electrical performance, compact and easy to install, reliable performance, safe and convenient to use. Its unique anti-condensate design plays a good role in pressure protection for safe and efficient operation of equipment.

Cautions
- The customer does not need to make any adjustments to the pressure transmitter before put it into operation.
- Before putting into operation, please check the threads and electrical connections strictly.
- For good results and reliability of use, check the mechanical and electrical connections frequently.
- If the pilot hole is clogged or the diaphragm is fouled, clean it with a solvent compatible with the transmitter's material of construction.
- Do not brush the pressure-sensitive diaphragm or poke the pressure hole with a hard object.
- In case of electromagnetic interference, ground the transmitter housing well.
