Description

Offered in CSA and Cenelec approved intrinsically safe or general pur-

pose configurations, the two-wire ultrasonic transmitter provides non-

contact level measurement up to 18’ or 5.4m, and is ideally suited for

challenging corrosive, slurry or waste liquids. The transmitter is typical-

ly selected for atmospheric bulk storage, day tank and waste sump

applications located within a classified hazardous area. Media exam-

ples include diesel fuel and hydrochloric acid. The transmitter is cali-

brated in less than a minute using the LCD display, 4-button interface

and intuitive calibration menu. All user set points are held in non-

volatile memory. In the event of acoustic signal loss, the transmitter will

hold the current output at the user designated safe state.
