Contrec 220i Level and Contents Display
Contrec 220i ATEX level monitor is intrinsically safe Level and Contents Display, it is certified by European ATEX/IECEx standards and CSA US/C standards of US and Canada. Contrec 220i Level Monitor accepts a 4-20mA signal from a wide range of level sensors. Input from level sensors can come from pressure transmitters, ultrasonic sensors, or capacitance probes.
Contrec level monitor comes with a large LCD to display both level and tank contents up to 7 digits and 12mm high. Contents are displayed with 42 digit resolution and trailing zeros. Equip with 4 open collector outputs suitable for driving DC solenoids or external relays. The outputs provide high, high-high, low, and low-low flow alarms. Hence the solid-state relay outputs provide up to four level alarms and a 25 point non-linearity correction table. Hence, the level monitor is programmable to fit most tanks.
Contrec 220i is loop-powered from 4-20mA current loop; therefore, no external power or batteries required. The instrument is fully programmable with setup parameters such as span, offset, alarm levels, etc. Contrec level monitor has a non-volatile memory that will retain all data for more than 10 years without power. The housing for the level monitor is polycarbonate and IP67 (NEMA 4X). Therefore, it is completely watertight. This level monitor comes with a standard wall mounting. Alternatively, 2″ pipe mounting and panel mount are also available.
