Level Controls

We manufacture monitors and controls for both solid and liquid applications including both on/off alarm switches and continuous level monitors and transmitters. They utilize a radio frequency capacitance system that offers accurate readings and low maintenance.  As the level rises or lowers, the probe detects changes in the capacitance field. This type of system features corrosion resistance, no moving parts, and easy set up and calibration. Arjay Engineering Ltd. has been in business since 1982, and we have the technical expertise to supply the optimal level controls for your operations.

Level controls

All our controls feature explosion proof housing and probes. Our remote units feature a control panel mounted away from the process, where operators can safely perform all the calibration, diagnostics, and wiring. Our level switches allow you to set high and low level points on the probe, and can be used for pump and valve control.

On/off level alarm switches:

2882-LS High and Low Level Alarm: A probe mounted switch with single point alarm.

2852-LS High and Low Level Alarm: A two-point level switch with remote electronics. Both alarm set points have differential control.

Continuous level monitors/transmitters:

2880-LT Probe Mount Level Transmitter: A probe mounted transmitter that uses 4-20 mA. It has variable probe length. Calibration is performed with a simple keypad and display.

2852-LT Remote Mount Level Monitor:  A remote mount level monitor that provides proportional output of 4-20 mA. It uses RS-485 communication and type 4 electronics. It offers two SPDT relay set points with full differential.

4100-LEV Level-Ease Level Monitor: A monitor that provides display of levels, four relays, and proportional 4-20 mA output. It offers a convenient way to monitor multiple tanks. It can display hourly, daily or monthly trends.

Level control expertise

We have over 30 years’ experience. Our professionals know level controls inside and out. We have the capability to offer custom design, engineering and assembly services. We also provide instruments such as oil-in-water monitors, gas detectors, plugged chute detectors, leak alarms, and spill alarms.

Level control industry applications

Our equipment is typically used for pump and valve control, to provide alarms when product conditions are too high or low, and to alert of possible overflow and dry conditions. We have experience meeting the requirements of industries such as oil and gas, chemical storage, sewage treatment, water treatment, pharmaceutical and more.
