Bourdon tube pressure gauge, copper alloy Standard version Models 111.10, 111.12

Product catalog summary

Applications: The WIKA model 111 pressure gauges are intended for use with gaseous and liquid media that are not highly viscous or crystallizing and do not corrode copper alloy parts. They are applicable in pneumatics, heating and air-conditioning technology, and medical engineering.

Special Features: These gauges are reliable and cost-effective, adhering to EN 837-1 or ASME B40.100 standards. They are available in nominal sizes from 40 mm to 160 mm, with scale ranges up to 400 bar (6,000 psi).

Description: The model 111 gauges use a Bourdon tube measuring system, offering various combinations of case materials, process connections, nominal sizes, and scale ranges. They are suitable for industrial applications and can be mounted in control panels with different mounting options.

Specifications: Available in different nominal sizes and connection locations, with options for plastic or steel cases. They feature a Bourdon tube measuring element made of copper alloy, with accuracy classes of 1.6 and 2.5 according to EN 837-1 and ASME B40.100 standards. They can withstand medium and ambient temperatures from -20 to +60 °C.

Approvals and Certifications: Compliant with international standards, including the EU Pressure Equipment Directive and NSF/ANSI/CAN 61-G for drinking water system components. Optional approvals are available for specific countries and applications.

Accessories: Include adhesive label sets, seals, syphons, overpressure protectors, and needle valves.

Overview: The document provides technical specifications and ordering information for various valve types, including the IV2 Block-and-bleed valve, IVM Monoflange, and BV Ball valve, each with a specific data sheet for detailed information.

Valve Types:

IV2 Block-and-bleed valve: Detailed specifications in data sheet AC 09.19.
IVM Monoflange: Available in process and instrument versions, with specifications in data sheet AC 09.17.
BV Ball valve: Available in process and instrument versions, with more information in data sheet AC 09.28.

Ordering Information: Specify the model, nominal size, scale range, process connection, connection location, and additional options when ordering. A configurator is available for standard articles to assist in selection.

Bourdon tube pressure gauge, copper alloy Standard version Models 111.10, 111.12-1

WIKA data sheet PM 01.01 ■ For gaseous and liquid media that are not highly viscous or crystallising and will not attack copper alloy parts ■ Heating and air-conditioning technology Special features Fig. left: model 111.12, back mount Fig. right: model 111.10, lower mount (radial) The model 111 pressure gauges are based on the proven Bourdon tube measuring system. The deflection of the Bourdon tube is transmitted to a movement and indicated. The modular design enables a multitude of combinations of case materials, process connections, nominal sizes and scale ranges. Due to the high variance, the instrument is suitable for use in a wide range of applications within industry. For mounting in control panels, the pressure gauges can, depending on the process connection, be fitted with a surface mounting flange or with a triangular profile ring and mounting bracket. The standard version of the model 111 is manufactured, cost-optimised on modern production lines, in volumes of several million instruments per year.
