A Remote Transmission Pressure Gauge is designed for applications where operators need both a clear on-site pressure reading and a remote electrical signal for monitoring or control. It keeps the familiar dial display of a mechanical pressure gauge while allowing pressure data to be transmitted to a control panel, secondary instrument, PLC or automation system.
This makes it a practical choice for pump systems, water supply lines, boilers, compressors, hydraulic equipment and industrial pipelines where pressure must be checked locally and monitored remotely at the same time.
What Is a Remote Transmission Pressure Gauge?
A remote transmission pressure gauge is a pressure measuring instrument that converts the movement of the pressure sensing element into an electrical signal. Depending on the model, it can be supplied as a resistance remote pressure gauge, potentiometer type pressure gauge, or electronic output pressure gauge.
Compared with a standard pressure gauge, it does more than show pressure on the dial. It can also send a signal to remote equipment, helping users monitor pressure changes without standing beside the pipeline or machine.
How It Works
Inside the gauge, pressure from the measured medium acts on the sensing element, usually a Bourdon tube. The mechanical movement drives the pointer for local indication. At the same time, the built-in transmission component converts this movement into an electrical output signal.
Common output options may include resistance signal, 4–20mA, 0–10V or other customized signal types, depending on the selected model and control system requirements.
Key Features
Local Reading and Remote Monitoring
The dial allows workers to check pressure directly on site, while the remote output signal can be connected to a control cabinet, data acquisition device, PLC or display instrument.
Suitable for Industrial Pressure Control
The gauge is suitable for pressure monitoring in water, air, oil, steam and other compatible media. For special media or harsh working conditions, stainless steel wetted parts or customized structures can be selected.
Stable Mechanical Structure
The gauge keeps the simple and reliable structure of a mechanical pressure gauge. It is easy to install, easy to read and suitable for long-term use in industrial environments.
Flexible Output Options
Different remote signal types can be selected according to the control system. Resistance output is often used with matching secondary instruments, while 4–20mA or 0–10V output is widely used in automation systems.
Easy Integration with Control Panels
The product is commonly used with pump control panels, pressure monitoring systems, water supply equipment, boiler systems and other electrical control devices.
Typical Applications
Remote Transmission Pressure Gauges are widely used in:
- Pump stations and water supply systems
- Fire pump and booster pump systems
- Boiler and heating systems
- Air compressors and pneumatic equipment
- Hydraulic stations and lubrication systems
- Industrial pipelines and process equipment

Why Choose Our Remote Transmission Pressure Gauge?
Our remote transmission pressure gauge is built for industrial users who need a simple but dependable pressure monitoring solution. It helps reduce manual inspection work, improves system visibility and allows pressure changes to be observed from a control room or control cabinet.
For pump systems and pipeline equipment, it can provide a more complete monitoring method than a standard pressure gauge. Operators can still read pressure on site, while the control system receives remote pressure information for display, recording or further control.
Remote Transmission Pressure Gauge vs. Electric Contact Pressure Gauge
A Remote Transmission Pressure Gauge is mainly used for continuous remote pressure monitoring. It sends a pressure-related electrical signal to another instrument or control system.
An Electric Contact Pressure Gauge is mainly used for pressure limit control. When pressure reaches the preset upper or lower limit, the contact can trigger an alarm, pump start/stop or other switching action.
Simply speaking:
Remote transmission pressure gauge = pressure signal transmission
Electric contact pressure gauge = pressure limit switching control
If your system needs continuous pressure data, choose a remote transmission pressure gauge. If your system only needs high/low pressure alarm or start-stop control, an electric contact pressure gauge may be more suitable.
How to Select the Right Model
When choosing a remote transmission pressure gauge, please confirm the following information:
- Measuring range, such as 0–0.6MPa, 0–1.0MPa, 0–1.6MPa or other ranges
- Output signal type, such as resistance signal, 4–20mA or 0–10V
- Dial size and installation direction
- Process connection thread
- Measured medium and working temperature
- Whether stainless steel material is required
- Whether the gauge will be used with a control panel, PLC or secondary display instrument
Providing these details helps us recommend a more suitable model for your working conditions.
FAQ
What is a remote transmission pressure gauge used for?
It is used to measure pressure on site and transmit pressure information to a remote display, control cabinet, PLC or monitoring system.
Is it the same as a pressure transmitter?
Not exactly. A pressure transmitter usually focuses on electronic signal output. A remote transmission pressure gauge combines a mechanical dial display with remote signal output, so users can read pressure locally and remotely.
Can it be used for pump control systems?
Yes. It is commonly used in pump stations, booster systems, water supply equipment and control panels where pressure needs to be monitored from a distance.
What output signal can be supplied?
Common options include resistance signal, 4–20mA and 0–10V. The final output type should be selected according to the matching instrument or control system.
Can it measure steam or oil pressure?
Yes, if the material and pressure range are suitable for the medium. For high temperature, corrosive or special media, customized materials or additional protection may be required.
