The YNTZ Series Seismic Resistance Remote Transmission Pressure Gauge build upon the YTZ product line by incorporating measures such as filling with damping fluid and installing damping devices, thereby enhancing their seismic resistance, improving the accuracy and stability of readings, and broadening their range of applications. 
The above series of instruments can be combined with diaphragm isolators to form diaphragm-type remote pressure gauges, which are suitable for measuring the pressure of media that are highly corrosive, highly viscous, and prone to crystallization.

The YTZ series Resistance remote pressure gauge is suitable for measuring the pressure of media such as liquids, gases, and steam that do not corrode the instrument’s components. This product can both indicate pressure locally and transmit the measured value—in the form of an electrical signal—via a slide-wire resistive transmitter installed inside the gauge to secondary instruments located remotely from the measurement point, thereby enabling centralized monitoring and long-distance control. 

Application

• Built-in sliding-resistor transmitter converts pressure into an electrical signal.
• Supports remote transmission to secondary instruments, enabling centralized monitoring and remote control.
• It also features on-site pressure indication for convenient field viewing.
• Applicable to multiple industries including petroleum, chemical engineering, power generation, food, pharmaceuticals, and environmental protection.

Working Principle

The operating principle of the mechanical part of the instrument is the same as that of a typical bourdon
tube pressure gauge. Inside, there is a resistor transmitter mounted on the gear transmission mechanism.
When the sector gear shaft in the gear transmission mechanism deflects, the brush of the resistor transmitter
also deflects accordingly. As the brush slides along the resistor, the change in the measured pressure value is
converted into a change in resistance value, which is then transmitted to the secondary instrument, indicating
the corresponding pressure value. Simultaneously, the primary instrument also indicates the corresponding
pressure value.
