Contrec 120A Level Indicator is an instrument operating based on the microprocessor. Hence, it accepts a 4-20mA input and displays level and contents. Level display in a bar graph as 0 to 100%, while the contents are a 7 digit numeric display. In addition, it can be also spanned in any engineering unit. Contrec Level Indicator is also a high accuracy model.
The level indicator is operating with analog level sensors. Contrec Level Monitor is having an IP67 weatherproof case, tactile keyboard, and various mounting options. As a result, it is a very versatile unit. The instrument is using 4-20mA current loop power as the power source. Therefore, requires no external power or internal batteries. Solid-state relay outputs provide up to four level alarms and a 25 point non-linearity correction table, hence it allows the instrument to program to fit most tanks.
Contrec 120A Level Monitor is fully programmable with setup parameters such as span, offset, alarm levels, etc, and stored in non-volatile memory. The memory can retain all data for more than 10 years without power. Calculation constants can also be set from the front panel and store in a non-volatile memory that retains data indefinitely. The Contrec 120A Level Monitor build with a rugged enclosure which is IP67 (NEMA 4X) polycarbonate. Hence, the enclosure is completely watertight. The level monitor comes with a standard wall mounting bracket. Meanwhile, a 2″ panel and pipe mounting bracket are available as an option.
