H-Series Tank Level Sensor (HW-RL3 & HW-RL4)
Brand: OleumTech CorporationThe RS485 Resistive Tank Level Sensors by OleumTech® are part of the H Series line of high quality instruments that deliver unrivaled performance, reliability, and accuracy in hazardous locations as well as under harsh, extreme environmental conditions.
With over two decades of innovation and manufacturing expertise, OleumTech’s Resistive Level Sensors are the company’s flagship level monitoring solution that offers industry’s leading 3-in-1 monitoring capabilities: product (oil), interface (water), and temperature.
Furthermore, the HW-RL3 RS485 Modbus Transmitter is equipped with two discrete inputs for connecting to dry contact or open-drain output/NPN sources delivering 5-in-1 monitoring capabilities.
The HW-RL3 also has the ability to calculate and report volume and tank full percentage data.
OleumTech’s patented Resistive Level Sensors are offered in both flexible (PTFE) and rigid (316 SS) materials in various lengths.
The H Series ultra-high-performance level gauging solution can communicate with any Modbus master or LevelMaster ASCII device via RS485 Serial connection.
The low-power Resistive Level Sensors can be multi-dropped of up to 16 sensors.
The Resistive Level Sensors are certified for use in Class I, Division 1 (Zone 0) hazardous locations and are Intrinsically Safe, making them one of the safest products in the world.
