UHF Explosion-proof transmitter of Stainless steel material - UHF

Application:

A handheld communicator and local push-buttons with a LCD digital display offer the operator the potential to calibration. without ever leaving the control room. used as float level gauge, act in concert with flap level gauge.

Function principle:

The UHF-HT series instrument is a 2 wire, loop-powered level transmitter with HART communication. Measuring principle

The resistance chain with the reed contacts are built in a pipe made of Stainless Steel. According to the movement of the float, the float magnet closes one reed contact which produces a resistance proportional to the height of the liquid in the tank.

You get a near-analogous output signal, with a resolution of about 10 mm, 20mm, or 5mm.

Then the reed chain with an R/I measurement transducer can be changed without interrupting the operation. change the level to 4~20mA proportional.The resistance chain receives it’s power supply from the transmitter. The 4...20 mA transmitter output signal can be transferred to an indicator or can be used to drive alarm contacts.

Advantage:

The UHF-HT Series level transmitter is a digital level transmitter with HART communication. It is designed for ease of calibration and set-up, with superior technical performance. A handheld communicator and local push-buttons with a LCD digital display offer the operator the potential to calibration.without eve leaving control room.

Technique Data:

Max. medium temperature: 120 °C

For higher temperature(up to 350°C) need Heat protection(only with magnetic level gauge)

Protection pipe: 19 mm×1mm

Resolution 10mm 20mm 5mm

Material: SS,or 304SS or other matrial

Enclosure: IP65

Out signal: 4~20mA (HART oppotional)

Power supply: 12~36VDC two-lines

Approval: ExdIICT5(oppotional)

It can be used as a float level gauge or be used with magnetic level gauge as a level transmitter, This so-called “Reed-chain” is mounted on the float chamber with tube clamps.
