P/I Transducer PIT6000

The PIT6000 is an air pressure to current transducer, used as a hydrostatic pressure level sensor. It converts the air pressure input of 0-10 kPa to a 4-20 mA current loop output, for industrial and laboratory applications such as liquid level or air pressure analogue measurement. It can be used in open tanks with level height from 10 cm up to 500 cm by using a hydrostatic pressure analog sensor and a 4-20 mA analog output, available for any further use.

The sensor is a thin deflation tube, clamped on the wall of the tank with its nozzle immersed into the liquid. A small quantity of air is provided to the tube via air pipes through the device’s internal air flow regulator. This amount of air deflates from the tube into the liquid in a form of bubbles, with variable difficulty according to the height of the liquid level. Free deflation corresponds with liquid absence and for any other level height, a different hydrostatic pressure is applied to the air inside the tube.

An air gauge sensor compares the applied pressure with the atmospheric pressure and the result of this comparison drives a current loop transmitter to a 4-20 mA output.

It is designed to be installed at the inside of an electrical control panel, placed on an Ω-type mounting rail (DIN NS32/NS35) and it is composed of an electronic board, various air-mechanical components and a thermoplastic casing, suitable and approved for electrical and electronic devices.
