Overview
LONN-1LX is an all-sealed input diffused-silicon level measuringinstrument which adopts the high-accuracy and high-stability pressure sensitivecomponents with stainless steel isolation diaphragm. With the reasonablestructure design and advanced micro-processing technology, it is able torealize linear error compensation and temperature drift compensation. Besides,it is equipped with a waterproof cable with ventilation duct making the sensor'sback-pressure cavity connecting to the atmosphere. Through sealed package it ismade into an industry-standard 4 ~ 20mA or 0.5 ~ 4.5V or RS485 signal integrativeproduct.
Product features
1.Wide measuring range: 0~1m~200mH2O
2.Multiple outputs available: 4-20mA, 4-20mA+Hart, 0.5-4.5V, MODBUS-RTU/RS485
3.Digital compensation technology and high accuracy
4.Good temperature drift ≤0.01%FS/ºC
5.Anti-condensation technology and anti-interference design
6.All-welded structure and protection rating up to IP68
