PMP-066, -092, -095, -099 level sensors
Application
PMP-066, PMP-092, PMP-095, PMP-099 level sensors with “W5DНЗ” output are designed for control of 1 … to 3 tank infil levels in conjunction with MS-P…,MS-3… Signal devices. Level sensors in a set with signal device are intended for use in technological systems for automatic control of pumps as well as for tanks overfill prevention, double wall tanks interstitial tightness control and for many other purposes, requiring highest measuring system reliability. Measurement reliability is achieved by: - doubling of main units (floats, reed swtiches), - automatic control of functionality (MS-…signal device ability).
PMP-066 is designed for control of three high levels at oil and gas stationds (H=90%, HH=95%, E>95%), gas station (H=80%, HH=85%, E>85%) or other purposes, requiring high measuring reliability and overfill prevention.
PMP-092 level sensors are designed for double wall tanks tightness control and provides control signal emission during expansion chamber level lowering. Have two control low levels.
PMP-095 level sensors are designed for control of three levels: PMP-095 NA-N-V - two low and one high level, а PMP-095 N-V-VA - one low and two high levels. Used in oil and gas station and other objects requiring threshold levels control or automatic level adjustment.
PMP-099 depending on modification, may control one or two levels:
«PMP-099- … -L…" – one lower level;
«PMP-099- … -H…» – one high level;
«PMP-099- … -H… - HE…» – two high levels;
«PMP-099- … -LE… - L…» –two lower levels;
«PMP-099- … -L… - H…" – lower and higher.
Design, principle of operation
Level sensors are similar to PMP-052 sensors with W5DNC output in terms of design and operation principle . PMP-066..-099 are always manufactured with smaller housing of type «M».
