200 psi

35 psid to 150 psig supply pressure at control inlet.

Pressure above 300% nominal range (overrange) will result in damage to the transmitter (200% may cause a shift in calibration). Burst pressure is 200 psi and will cause catastrophic and physical failure of the pressure element.

The KING-GAGE® D/P Transmitter is also offered in a hybrid version combined with an air flow control for pneumatic sensors or downpipe (bubbler) systems. These combination units allow for direct 4–20 mA signal from the tank using the integrated differential pressure transmitter.

D/P Sensor Controls are designed for use with KING-GAGE® pneumatic diaphragm sensors. The air control portion of these units creates a 1:1 pneumatic pressure directly proportional to liquid depth in the tank. Acting as a force balance, the pneumatic pressure offsets the hydrostatic pressure exerted against a diaphragm at the tank. The electronic transmitter then converts this pressure into a 4-20 mA output signal.

D/P LiquiSeal™ Controls and D/P Purge Controls are used in conjunction with a downpipe (or bubble tube) extending down through the liquid contents of the tank. This type of sensor also acts as a force balance. A continuous purge of compressed air into the pipe displaces the liquid and creates a pneumatic pressure equivalent to hydrostatic head pressure. The transmitter converts this pressure into a 4-20 mA output signal.

• Piezoresistive element for less frequent recalibration
• 4 mA to 20 mA two wire output for monitoring or control
• Better than ±0.02% span repeatability

Liquid level gauging demands a high degree of accuracy and repeatability. This is especially true for quality control in batch processing operations. That is why KING-GAGE® D/P Transmitters are specifically designed to provide optimal performance in tank gauging applications. They utilize a precision piezoresistive sensor element that provides longer term stability. Guaranteed accuracy is within ± 0.2% F.S. and repeatable to within ± 0.02% of calibrated span.

All KING-GAGE®, a NOSHOK Company products are guaranteed to be free from defects in material and workmanship for one (1) year from the date of purchase.

Repair Services Warranty: 90 days limited warranty.
