Loop Powered Ultrasonic Sensor

LPU-2127

Hazardous Area Certified with Integrated Keypad

The LPU-2127 features a built in keypad and LCD display for easy programming that can be done entirely through the keypad.

Description

We designed the LPU-2127 for easy set-up. Wiring is fast, and programming is done entirely through the integrated keypad.

Easy Set-Up
We designed the LPU-2127 for easy set-up. Wiring is fast, and programming is done entirely through the integrated keypad.

Tough and Safe
With CSA hazardous location certification, and a durable housing with high chemical compatibility, this ultrasonic sensor performs well under stress.

No Fuss
The LPU-2127 is loop-powered for faster, more efficient wiring, and the easy interface and keypad eliminate the need for a computer. The sensor is virtually maintenance-free!.
