YTT remote pressure gauges

◆ Model: YTT100 YTT100A YTT150 YTT150A

◆ Application: This type of instrument is suitable for measuring the pressure of liquids, gases or vapors without explosion hazard, no crystallization, no solidification, and no corrosive effect on copper and copper alloys.

In addition to the local indication of the pressure value, the instrument can also continuously output (0~10) mA or (4~20) mA DC signal, which can be transmitted to the control room at a long distance, and can be used with intelligent digital display instruments to form an automatic system for display, recording, adjustment and control.

The instrument has undergone a major transformation inside, the original differential transformer has been removed and replaced with a diffusion silicon voltage-sensing element, so that the local display part and the signal output part have become two independent systems, and the output signal accuracy and reliability have been greatly improved, and the accuracy can reach 1.0 or even 0.5 level.
◆ If it is necessary to make a shockproof type pressure gauge, it can be filled with glycerin or silicone oil.
