Monitoring technique

Level sensing relay MK 9151

varimeter

• According to IEC/EN 60 255, DIN VDE 0435-303

• 3 probe connections for 2-point and 1-point level control

• Also for use as moisture detector

• High interference resistance of the measuring circuit, which is

isolated from the mains

• Max. wire length to the probes: 1500 m

• Large setting range: 2 ... 450 kΩ

this permits differentiation between fluid and foam

• Adjustable response and release time delay: 0,2 ... 20 s

• Programmable for open circuit operation (without bridge)

or closed circuit operation(bridge X1-X2 or X1-COM)

• For auxiliary voltages of 24 ... 415 V AC or 24 V DC

• Green LED for operation

• Yellow LED for contact position

• 1 or 2 changeover contacts

• Also available with sealable transparent cover

• Available with safe separation according to IEC/EN 61 140,

IEC/EN 60 947-1

Application

COM X1 11 - 12

• Level monitoring and control for conductive liquids and powders,

e.g. maximum and minimum filling levels, overfilling and protection

against dry running

• Monitoring and control of the mixing ratio of conductive liquids

• General resistance monitoring tasks, e.g. limit temperature

detection with PTC

Notes

All commercially available probes are suitable.

The reference probe for level measurement is generally located at the

lowest point of the container and must always be connected to the "COM"

terminal. The container itself can be used as a reference probe if it

consists of conductive material.

1-point level control (see Figure) is especially suitable for protection

against overfilling and dry running on containers with a free inlet/outlet.

In this configuration, all that is required besides the reference probe

"COM" is the "MAX", which must be located at the desired limit level. The

output relay switches over after the set delay time if the fluid level

exceeds or falls below the limit level, which permits fluid to be pumped

out or added.
