Time Electronics 7190
A benchtop pneumatic pressure pump that is a dual pressure source with the ability to achieve high pressures with minimal effort. It provides both 95% vacuum and pressure to 140bar (2000psi). The long pump lever with ergonomic grip enables smooth generation to high output pressures and a high-quality screw press is incorporated to allow fine adjustment settings within 0.1mbar (10Pa). The 7194 can also be used to generate low pressures (600mbar) without pumping.
An isolation valve shuts-off the pump from the system under pressure to keep the output stable under calibration. A built-in gas-liquid trap protects the pump from moisture and dirt. Any residual liquid in the pump is vented out via the vent port which incorporates a hose connection to allow collection of liquids. For calibration applications the double output manifold provides finger-tight connections for a reference gauge and device under test.
The 7194 is comfortable and simple operation, with features that make it ideal for calibrating pressure transducers, precision pressure gauges, and other pressure instruments. It is particularly suitable for applications where high pressure is required without the use of hydraulic pumps or nitrogen cylinders. It is also ideal for use as a benchtop gauge comparator.
To accompany the pump Time Electronics offer a range of digital pressure gauges, including the TEG-G140b model that covers the range of the pump with 0.2/0.1/0.05/0.025% FS accuracies available. Also available is the 7078 auto-ranging digital pressure gauge with vacuum to 200bar range and 0.1% accuracy of setting.

Time Electronics 7190
The 7190 is a hand operated pressure pump designed to generate either vacuum to -0.4 bar (-6psi) or pressures to 0.4bar (6psi). A high-quality screw press is designed for fine pressure adjustment, with adjusting resolution up to 0.0001mbar (0.01Pa).
To reach the pressure stability as high as possible during the micro-pressure calibration, an isothermal bellows chamber is designed for reducing the possible heat effects such as environmental temperature change. The 7190 is designed without a non-returning valve meaning minimal maintenance is required. Two finger-tight connectors installed on the pump allow the user using fingers to connect and disconnect the reference gauge and devices under test quickly and easily without the need for PTFE tape or wrenches.
The 7190 is ideal for applications requiring accurate low pressure testing and calibration.It can be used in calibrating low pressure gauges, transmitters, or other pressure measuring instruments. To accompany the pump a wide range of precision digital pressure gauges are available. The TEG-C400mb covers the full range of the pump (0 to ±400mbar) with accuracies of either 0.2%, 0.1%, 0.05%, or 0.025% of full scale.
