UPB9 membrane pressure transmitter 4-20ma
Discriptions:
UPB9 pressure transmitter uses high quality pressure sensors with isolated stainless steel diaphragm as sensing elements, it is tested by computer automatically and made laser trimming compensation for zero and sensitivity.
The output of UPB8 is amplified to 4~20mA standard output by using special amplifier, simultaneously the output signal can be displayed through LCD indicator at working site.
After long-term aging tests and stability tests, this product's performance is very reliable, it is suitable for the pressure measurement and control in bad working conditions, and presently widely used in petroleum, chemical industry, metallurgy,
electric power etc.
Features:
•31/2 LED displaying at working site, simultaneously give 4~20mA signal output
•High performance-to-price ratio, high accuracy, long-term stability
•Electric shell is cast-aluminium material , IP65 protection
•Reversed protection, current limiting protection
•Anti-corrosive, the anti-attrition, the anti-impact
•Flush membrane and the tantalum diaphragm option
