The WIKA 111.10 is a general-purpose mechanical pressure gauge using a proven Bourdon tube measuring system. Pressure causes the tube to deflect, and the movement transfers this motion to the pointer for visual indication. Designed to meet EN 837-1 and ASME B40.100, it is suitable for many standard pressure-monitoring tasks.
Key Features
- Bourdon tube measuring system for mechanical pressure indication
- Copper alloy wetted parts and movement
- Lower-mount (radial) process connection
- Available in 1½", 2", 2½" and 4" dial sizes
- Accuracy: ±3/2/3% of span, ASME B40.100 Grade B
- Multiple pressure, vacuum and compound ranges
- Black plastic case as standard; selected alternative case options available
- Optional glass window, drag pointer and special connections, depending on configuration
Suitable Applications
- Hydraulic and pneumatic systems
- Pumps and compressors
- Water systems and pressure regulators
- General industrial equipment
- Fire sprinkler systems, when the specified configuration is suitable
- Other applications using media compatible with copper alloy wetted parts
How It Works
The gauge uses a curved Bourdon tube that deforms under pressure. This movement is mechanically transferred to the pointer, which indicates the measured pressure on the dial. No external electrical power is required.
Technical Highlights & Selection Considerations
- Pressure range: Available ranges extend from vacuum and compound scales to high-pressure ranges up to 6,000 psi (400 bar), depending on the selected version.
- Dial size: Choose 40, 50, 63 or 100 mm according to viewing distance and available installation space.
- Process connection: Standard lower-mount connections include 1/8" or 1/4" NPT, depending on the model.
- Media compatibility: Confirm that the process medium will not clog the pressure connection or attack copper alloy components.
- Operating conditions: Standard ambient temperature range is -40°F to 140°F (-40°C to 60°C); maximum media temperature is 140°F (60°C).
- Working pressure: For continuous or fluctuating pressure, follow the manufacturer’s specified limits rather than selecting a gauge solely by its maximum scale value.
- Configuration: Confirm the case material, scale units, connection size and any required options before ordering.
Frequently Asked Questions
Q1: What is the WIKA 111.10 used for?
It is used for local pressure measurement in hydraulic and pneumatic systems, pumps, compressors, water systems and other compatible applications.
Q2: Does the 111.10 require a power supply?
No. It is a mechanical Bourdon tube pressure gauge and does not require external electrical power.
Q3: What pressure ranges are available?
Ranges vary by configuration, from vacuum and compound ranges to pressure ranges up to 6,000 psi (400 bar). Confirm the required range when ordering.
Q4: What is the accuracy of the 111.10?
The US product specification lists ±3/2/3% of span in accordance with ASME B40.100 Grade B.
Q5: Can it measure corrosive fluids?
Only when the medium is compatible with the gauge’s wetted materials. The standard model uses copper alloy wetted parts and is not suitable for media that attack copper alloys.
Q6: What information is needed to select the correct gauge?
Specify the pressure range, dial size, process connection, scale units, medium and operating conditions. Also confirm any special case or accessory requirements.
