The PT4510 was designed for low-level applications of up to 400 inches,
while the PT4500 is available in ranges up to 100psig. To deliver
accurate level detection, a transmitter is placed at the bottom of the
tank holding the liquid, and the transmitter converts the pressure
reading to an analog 4-20mA output signal. The electrical connection to
the transmitter is routed through the top of the tank and contains
power and signal wires. These IP 68-rated, stainless steel pressure
transmitters carry UL/cUL 913 approval for use in Class I, Division 1,
Groups C and D locations when installed with an approved barrier. Turck Inc.www.turck.us800.544.7769
