Description
1. Introduction to the Solid Front Bourdon Tube Pressure Gauge
The Bourdon tube pressure gauge, Solid Front Design MT-P110ST, is a high-reliability and safety-focused mechanical pressure measurement device engineered for demanding industrial environments. This pressure gauge is specifically designed to provide enhanced operator protection, making it ideal for applications involving high pressure, pulsation, or potentially hazardous media. With a solid front barrier and blow-out back construction, the MT-P110ST ensures maximum safety in case of internal failure, safeguarding both personnel and equipment.
Built using the proven Bourdon tube measuring principle, the gauge converts internal system pressure into pointer movement, providing a clear and accurate reading on a well-defined dial face. The solid front construction ensures safe pressure monitoring across industries including petrochemical plants, hydraulic systems, compressor manufacturing, process automation, water treatment facilities, and general mechanical maintenance.
2. Dial Size Options for Different Operating Environments
The Bourdon tube pressure gauge, Solid Front Design MT-P110ST is available in multiple dial sizes, enabling users to select the most suitable version for readability and installation space requirements. Available dial sizes include:
-
40 mm (1½″)
-
50 mm (2″)
-
63 mm (2½″)
The larger 63 mm dial version is ideal where high readability is required, such as on machine panels, pump stations, and wide industrial processing units. Meanwhile, the 40 mm version is suitable for compact installations or portable equipment where space is limited. Regardless of size, each dial face is clearly graduated for quick and reliable pressure reading.
3. Wide Pressure Range from Vacuum to High Pressure
One of the major advantages of the MT-P110ST model is its wide pressure measurement capability, offering a range from -1 bar (vacuum) up to 1000 bar, depending on configuration. This makes the gauge suitable for:
-
Low-pressure vacuum suction monitoring
-
Standard air or water pressure measurement
-
High-pressure hydraulic equipment and power units
The Bourdon tube mechanism ensures excellent repeatability and long-term performance, providing stable readings even under frequent pressure cycling. The gauge is suitable for non-corrosive liquids and gases that are compatible with copper alloy wetted parts.
4. Bottom Connection and Direct Mounting Configuration
For easy installation, the Bourdon tube pressure gauge, Solid Front Design MT-P110ST comes with a bottom process connection that supports direct mounting onto machinery, pipelines, manifolds, and pump housings. This eliminates the need for additional adapters or mounting brackets, saving time and reducing system complexity.
The ¼” NPT (National Pipe Thread) connection ensures compatibility with international industrial fitting standards. This makes the MT-P110ST suitable for both new system installations and replacement of existing gauges in maintenance programs.
5. IP65 Ingress Protection for Harsh Industrial Conditions
To ensure reliable operation in environments exposed to dust, vibration, oil mist, or water splashes, the gauge is manufactured with IP65 ingress protection. This means:
-
Dust penetration is fully prevented
-
The gauge is protected against jets or sprays of water from any direction
-
Internal mechanisms remain clean and stable for long operational life
IP65 performance makes the MT-P110ST suitable for outdoor use, humid facilities, mechanical workshop floors, construction machinery, and industrial processing areas.
6. Dry Execution or Glycerin Fillable Option for Vibration Resistance
The standard configuration of this pressure gauge is a dry execution, making it suitable for systems with stable, low vibration. However, the gauge is glycerin-fillable, meaning users can optionally fill the housing with glycerin to create a liquid-filled vibration-resistant gauge.
Benefits of glycerin-filled execution include:
-
Pointer stabilization for clear reading in vibration-heavy equipment
-
Reduced wear on Bourdon tube and internal movement components
-
Extended service life in pumps, compressors, and hydraulic circuits
This flexibility allows the Bourdon tube pressure gauge, Solid Front Design MT-P110ST to perform reliably in both standard and heavy-duty industrial operating conditions.
7. Solid Front Safety Construction for Operator Protection
The most important feature of the MT-P110ST is its solid front safety design. The internal mechanism includes:
-
A solid metal barrier between the dial and movement chamber
-
A blow-out back panel to release pressure safely in case of rupture
If internal failure occurs due to pressure overload or shock, the gauge is engineered to direct any released energy backward — keeping operators safe from frontal impact or debris. This makes the gauge particularly valuable for:
-
High-pressure hydraulic test stands
-
Oil and gas process lines
-
Chemical plant machinery
-
Industrial power systems
