Non-vented submersible level transmitter for absolute Pressure LMP633-NLN

LMP633 Non-Vented submersible level transmitter is applied when the atmospheric pressure is measured by a separate barometer and when the water level is calculated as the difference between the absolute value and the ambient pressure.

The sensor adopts the most advanced micro-processor technology with comprehensive linear error compensation and temperature error compensation to assure the highest precision of measuring result.

Signal transmitting module adopts transient voltage resistance protective circuits to assure operation regularly even under the harsh surge voltage environment. The seal of the cable adopts intensive cone plug sealing design to assure the long working life even under large mechanical load conditions during the installation and long-term use.

Features:

* Linear error and temperature error compensation of sensors achieve high precision.

* Fully potting design to eliminate the condensation phenomenon，dual-seal design to assure permanent air tightness

* Laser welding isolated membrane technology to assure the durability.

* Intensive cable seal to assure the long working life under large mechanical load conditions

* Built-in transient voltage protection circuit and optional of temperature measuring signal output.

* Optional various sensor technologies to satisfy the application of viscous and acid-based occasions
