Pressure Measurement Bench | ThermoFlux – 7015
Product Overview
The Pressure Measurement Bench ThermoFlux – 7015 is a freestanding laboratory unit combining a five-instrument manometer panel with an integrated Dead Weight Pressure Calibrator for comprehensive pressure measurement and calibration training. This Pressure Measurement Bench covers U-tube, inclined tube, and Bourdon tube manometry alongside digital pressure transmission (0–4 bar), with gauge pressure and vacuum measurement capability. The dead weight calibrator (piston area 254 × 10⁻⁶ m², ancillary masses up to 4 × 1 kg) produces traceable, reproducible calibration pressures transferred hydraulically to the gauge under test. Optional ThermoFlux – 7015 LabVIEW-based DAQ software with electronic sensors is available for Windows-based automated data acquisition.

Construction and Design
The Pressure Measurement Bench ThermoFlux – 7015 is constructed as a freestanding panel unit housing all manometric instruments, connecting infrastructure, and calibration equipment in a single assembly. The manometer panel mounts two tube-type manometers (U-tube and inclined tube, both 0–500 mm WC), two dial-type Bourdon tube manometers (0–100 mbar and –100–0 mbar), and a digital pressure transmitter (0–4 bar) with integrated display. All instruments are interconnectable via flexible hoses, enabling simultaneous multi-instrument comparison under identical applied test pressures. The plastic syringe and hand pump interface directly with the hose network to generate millibar-range test pressures without auxiliary equipment.
The Dead Weight Pressure Calibrator section of this Pressure Measurement Bench comprises a precision-machined piston and cylinder assembly mounted on levelling screws to ensure vertical alignment during operation. Hydraulic oil transfers the force applied by the weighted piston (piston area: 254 × 10⁻⁶ m²; piston mass: 0.5 kg) to the Bourdon tube pressure gauge under test. The piston rod is rotated during loading to eliminate static friction effects and ensure pressure accuracy. The supplied ancillary masses (1 × 0.2 kg, 2 × 0.5 kg, 4 × 1 kg) allow stepped calibration across the gauge's working range. The calibration Bourdon gauge features transparent construction for internal mechanism observation. The optional LabVIEW-based DAQ software integrates with an electronic sensor set for automated measurement and result calculation under Windows environments.

Frequently Asked Questions
Q1. What pressure measurement instruments are included on the manometer panel?
The panel includes a U-tube manometer (0–500 mm WC), an inclined tube manometer (0–500 mm WC), a positive-range Bourdon tube dial manometer (0–100 mbar), a vacuum-range Bourdon tube dial manometer (–100–0 mbar), and a digital pressure transmitter with display (0–4 bar).
Q2. How are test pressures generated on the ThermoFlux – 7015 Pressure Measurement Bench?
Test pressures in the millibar range are generated using the supplied plastic syringe and/or hand pump, which connect to the manometer panel via flexible hoses.
Q3. What is the purpose of the Dead Weight Pressure Calibrator?
The Dead Weight Pressure Calibrator generates a precisely defined, reproducible test pressure by loading the piston with known masses. The pressure (force ÷ piston area) is applied hydraulically to the gauge under calibration, allowing its readings to be verified and an error curve to be drawn.
Q4. What ancillary masses are supplied with the Dead Weight Pressure Calibrator?
The following masses are supplied: 1 × 0.2 kg, 2 × 0.5 kg, and 4 × 1 kg, in addition to the 0.5 kg piston mass.
Q5. Can the Pressure Measurement Bench be used without the optional DAQ software?
Yes. All four experiments can be performed manually using the panel instruments, syringe, hand pump, and dead weight calibrator. The ThermoFlux – 7015 DAQ software is an optional add-on for computerised data acquisition.
