Level alarms Sensor MS-3-2P, MS-3-2P-GS, etc.

The SVN-1 water and petroleum products detector is used to detect and differentiate liquid media in pump pits, fuel dispensers, process wells, inter-wall space of pipes and reservoirs of fire and explosive petrochemical and oil refining industries.

The MS-1ANVA-2P(P)-5P(HP) alarm device, complete with a level sensor PMP-112 (1ExdIIBT3), is designed to control the pumping pump in automatic mode and provides:

• turning on the pump at the lower (upper) level;
• turning off the pump at the upper (lower) level;
• monitoring the achievement of emergency levels (lower and upper) by giving an audible signal.

The MS-1NVMA-2ARU-3R alarm is complete with a level sensor PMP-152-W5NR-A-NA-N-V (or ...-N-V-VA-A) is designed to control two pumping pumps in order to automatically regulate the liquid level by:

• switching on the main pump at the first level;
• switching on the backup pump at the second level;
• disconnection of both pumps at the third level, and process control, which is ensured by the following functions: giving an audible signal at the fourth “emergency” level; indication of reaching control levels; indication of switching on pumps; monitoring and indication of the integrity of electrical circuits “sensor - alarm”.

The MS-3-2P, MS-3-2P-GS, MS-3-2P-DIN-DC signaling devices are designed to work together with level sensors having a W5DNZ output, indicating and signaling pressure gauges, vacuum meters, manovacuummeters. The alarm provides control and regulation of the values of the environment parameters:

• liquid level by 1...3 values,
• pressure according to 2 values.

The MS-3 three-channel alarm is designed to work with level sensors, indicating and signaling pressure gauges, vacuum meters, manovacuummeters and other signaling devices having normally closed contacts shunted by diodes at the output.

The MS-P signaling devices are designed to provide light and sound signals, control actuators when working together with level sensors having a W5DNZ output. Alarms are used at gas stations to prevent overflow of fuel tanks, to control the tightness of double-walled tanks with an expansion tank, to control the achievement of a minimum fuel level in tanks.
