The MTR conductive level control relay provides reliable, maintenance-free liquid level management in the harshest environments. Working with fail-safe sensing probes, it automatically controls pumps, alarms, or solenoid valves based on conductive level detection — no moving parts touch the process liquid.

What switching configurations does the MTR offer?

Eight programmable modes cover pump-up (fill), pump-down (discharge), alarm activation, and solenoid valve control. The adjustable conductive sensitivity accommodates liquids with widely varying conductivity. The configurable time delay prevents nuisance switching caused by wave action or turbulence.

How does the MTRA variant expand capability?

The companion MTRA adds an integrated alarm relay, enabling simultaneous pump-plus-alarm control or dual solenoid valve switching from a single unit. For critical applications, redundant backup can be built using one MTR or MTRA with two single sensing probes.
