EMR4-N Level Relay – Increased Safety with
Open-Circuit Protection
The EMR4-N level relays are used primarily to
protect pumps from running dry or for the control of
liquid levels. They operate by means of sensors
which measure conductivity, with one sensor
monitoring the maximum level and one sensor the
minimum. A third sensor is used for the chassis
potential.
The 22.5 mm wide EMR4-N100 device is suitable for
conductive liquids, and is provided with a switch to
select between Level control and Dry run protection
as required. This offers increased safety thanks to
the open-circuit design used in both cases.
Reliable monitoring of moving liquids with
on-delay function
The EMR4-N500 level monitor (installation width
45 mm) has an enhanced sensitivity and is therefore
also good for less conductive media. An integrated
on and off-delay function between 0.1 s and 10 s
ensures that even moving liquids can be monitored
reliably.
Features
- Level monitoring of conductive liquids
- Monitoring of mixing ratios
- LED status indication.
