APPLICATION
SPECIFICATIONS
CSA approved intrinsically safe for use in
general purpose or hazardous applications, 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. Push
button calibrated, the transmitter is typically
selected for atmospheric bulk storage, day tank
and waste sump applications located within a
classified area. Media examples include diesel
fuel and sulfuric acid.
