The Model 2110EX-A is the analog version of the Electrolab’s Explosion Proof Housing. This housing can be added to any Model 2100 Digital Level Sensor (RU Flex, Stainless Steel or Fiberglass) without the High-Level Shut-In option. 


The device is Class I, Division 1, NRTL certified explosion proof for use in hazardous locations/environments. The device is also certified to provide intrinsically safe output for use in hazardous locations. The barrier unit inside the housing actively limits the current and voltage to protect intrinsically safe equipment from power spikes. The barrier provides intrinsically safe power and communication or I/O lines for devices located in hazardous locations.



The Model 2110-A Explosion-Proof Housing (Analog Version) simplifies site design by allowing a Model 2100 Digital Level Sensor (RU Flex, Stainless Steel or Fiberglass) to meet electrical code and internal safety requirements without installing additional equipment. Step-down transformers, barrier boards, and other devices are not needed when the sensor is wired to explosion-proof conduit.

The housing offers 2-wire RS485 digital signals to a device located in a Class I, Division 1 location. The device also offers two, 4-20mA (3-wire configuration) analog signal output channels.

The device can handle voltage supplies from 12 to 24VDC max automatically.
