AVTECH’s Water Tank Level 1 Sensor (NC) monitors the rise and fall of water in a container (i.e. typically a large tank). The float and control weight are composed of chemically-resistant polypropylene; the 16' cable is coated with rugged PVC. Because this sensor uses a dual-point switch and differential height between switch states, you can use just one sensor to monitor two levels... both high and low.
Dimensions of the float switch are 5.1" H x 3.0" W. The control weight is 4" H x 2.25" W. The 16' attached cable with PVC coating has a protection rating of IP67 and NEMA 6. The switch state differential range is a minimum of 10" and a maximum of 50". Please see the Installation Note for more information.
There is also a Normally Open (NO) version of this sensor called the Water Tank Level 2 Sensor (NO), product # RMA-WTL2-SEN.
