Description

Brand: Tecquipment

Model: H30

Country of Origin: United Kingdom

Manufacturer: United Kingdom

Features:

• Should enable a range of practical investigations into manometer and Bourdon gauge pressure measurement techniques
• The equipment should enable students to fully investigate and compare the operation and characteristics of inclined and U-tube manometers and Bourdon-type vacuum and pressure gauges
• It also should include a separate Bourdon gauge with dead-weight calibration apparatus, enabling clear observation of the Bourdon tube mechanism
• The apparatus should consist of two units:
• A manometers and gauges unit
• A Bourdon pressure gauge calibration unit
• The manometers and gauges unit should be a framed structure with a backboard, holding a:
• Vertical U-tube manometer
• U-tube manometer with an inclined limb
• Bourdon gauge for measuring vacuums
• Bourdon gauge for measuring positive pressure
• Syringe assembly for pressurizing and reducing pressure in the measurement devices
• Each gauge and manometer should have a delivery point to connect to the syringe using plastic tubing (should be included)
• All connections should be push-fit and T-pieces should be provided to enable two instruments to be connected to one point
• The Bourdon pressure gauge calibration unit should consist of a piston, which is free to move vertically, in a close-fitting cylinder
• A transparent, flexible hose should connect the cylinder to the Bourdon pressure gauge
• The gauge and cylinder should be mounted on a common flat base
• The internal mechanism of the gauge should be clearly visible through the transparent dial
• During test, calibration weights can be placed onto the loading platform, which is an integral part of the piston assembly
• All air should be expelled from the system through a purge hole in the upper part of the cylinder
• The apparatus should be manufactured using materials and finishes carefully chosen to give the fullest protection against corrosion

Experimental Capabilities:

• A range of investigations into common pressure measurement techniques, including:
• Comparison of pressure measurement by manometer and Bourdon gauge
• Calibration of a pressure gauge
• Determination of gauge errors as a function of true pressure

Technical Parameters:

• Required accessories: Selection of weights for Bourdon gauge dead weight calibration, ‘T’ pieces, artery clamps, funnel and nylon tubes
• Bourdon gauge scale: Graduated in 0 ~ 200kN.m-2 in 10kN.m-2 intervals
• Typical gauge error: 1kN.m-2 over the entire range
• Dead weight tester load: 5~5.5kg
• Bourdon tube arc: 270° (approx.)
• Supplied weights: 1kg x 4, 0.5kg x 2 and 0.2kg x 1
• Printed operation manual
