CSS93420 Submersible Level Sensor
Description
CSS93420 submersible transmitter, use CSS series piezoresistive silicon oil-filled sensor as measurement component. According the relation between pressure, density and liquid level, the hydraulic transducers measure the liquid pressure which in direct ratio with depth of liquid, then via amplificatory circuit, the measured pressure is transferred to standard signal.
Special use cable, advanced seal technology, reliable amplify circuit and accurate compensation technic ensure the products have high accuracy and good capability of anti-leakage.
Feature
Wide range
Protection: IP68;
Various output signal
Good anti-leakage
Marking: ExiaIICT6

Application
Compatible with 316LSS,noncorrosive liquids
Apply in Petroleum industry, chemical industry, generating station, water supply, hydrology etc. those need to measure &control liquid’s level.

Ordering note:
1. Media must compatible with wetted parts.
2. There is two kinds of cable can be choose, one is common with gas tube, another is diesel oil &gasoline proof.
3. If the transmitter need LCD or LED display that the power supply should no lower than 20VDC。
4. To ensure the products can working reliable, we suggest that customer install lightning protection device and make sure products & power are earthed.
5. If the range is lower than 0.5m,the accuracy would be ±1%
6. Special requirement, such as strong shock, moment vibration, strong electromagnetism, radio frequency interference , please consult us.
Warranty:
Pressure transmitters have a limited one-year warranty to the original purchaser. Smart Sensor will replace or repair defective products free of charge. This warranty does not apply to any units have been modified, misused, neglected .
