Description

A bench top unit designed to introduce students to pressure, pressure scales and common devices available to measure pressure.
The equipment utilises a Deadweight Pressure Calibrator (DPC) to generate a number of predetermined pressures. This is connected
to a Bourdon gauge and electronic pressure sensor to enable their characteristics, including accuracy and linearity, to be determined.
The DPC consists of a precision ground piston and cylinder with a set of weights giving an operating range of 20 kNm-2 to 200 kNm-2.
The Bourdon gauge and pressure sensor are mounted on a manifold block with a separate reservoir to contain the hydraulic fluid (water for
safety and ease of use). Valves enable easy priming, restricted flow of water to demonstrate the application of damping and the connection
of alternative devices for calibration.

• Deadweight Pressure Calibrator with weights to generate a range of predetermined pressures. This is connected to a Bourdon gauge and electronic pressure sensor. The Bourdon gauge incorporates
  an arbitrary scale in addition to the pressure scale and a clear acrylic front face enables observation of the Bourdon tube and the operating mechanism. A reservoir with isolating valve enables the calibrator, Bourdon gauge and pressure sensor to be easily primed an arbitrary scale in addition to the pressure scale and a clear acrylic front face enables observation of the Bourdon tube and the operating mechanism.

• An electrical console houses the necessary electronics with current protection devices and an RCD for operator protection. A digital meter with selector switch displays the output from the pressure sensor, as well as the conditioned reading in engineering units. Corresponding signals are routed to an I/O Port for connection to a PC. An optional interface device with educational software package is available
• The Deadweight Pressure Calibrator, Bourdon gauge and pressure sensor are mounted on a common PVC baseplate. The electrical console is free-standing
• Pressure sensors, manometers or Bourdon gauges other than those supplied can be calibrated over the range 20 kNm-2 to 200 kNm-2
• A comprehensive instruction manual is included with a range of fully detailed laboratory teaching exercises
