Intelligent Level Transmitter
Model: CJBHZ
Description:
CJBH series liquid level transmitter adopts high precision silicon piezoresistive isolation film oil filling core body as a signal measuring element, according to the mathematical model of the relationship between the pressure and the measured liquid density, liquid level, it measures liquid pressure which is prortional to the depth of liquid level and it Outputs standard signals after signal processing circuit converts.Characteristics of air guide cable, advanced sealing technology, reliable specific amplification circuit and precise temperature compensation technology enables it to be high accuracy, small volume and good anti leak.Long-term immersion in liquid is reliable and stable.

Reminders when choose models
1. Pay attention to media which is measured is compatible with part of product
2. Anti-exposion products don't have LCD or LED dial
3. Order temperature transmitter with LCD or LED dial, the power voltage shouldn't be less than 20VDC
4. In order to keep stable performance, we suggest user to install lightning protection device 
5. If there is strong vibration, strong electromagnetic, RFI, please state before order and indicate in order.
