Compact manometer requires little power
A
Keller UK product story

Despite constant measuring and display the relatively small Lithium battery in Keller's da Vinci manometer lasts for nine months.
An extremely compact manometer with a digital display and very low power consumption make Keller's da Vinci line ideal for applications where a simple value display is adequate.
The manometers can be supplied in bar or PSI, and are available in the typical da Vinci oval housing or as a basic OEM module that can be integrated into the customer's system.
Despite constant measuring and display the relatively small Lithium battery lasts for 9 months.
The dV-1 offers a 0.5%FS resolution and employs digital logic.
This enables the gauge to make relative measurements without the need for a reference pressure input.
The manometer can be used in air and watertight housings.
A minimised price and striking simplicity make the dV-1 manometer ideal for high-volume production.
The dV-2 can be set to perform various measuring functions via two front panel buttons.
The internal microprocessor has great flexibility; thus enabling Keller to offer customised products for specific applications where large quantities are involved.
However, it is also possible to produce cost-effective small batches.
The dV-2 Cool was designed for monitoring tasks at coolant filling stations of refrigeration systems.
The temperature/pressure graphs of five cooling fluids are saved in the programme and the curve for the coolant in use can be selected by pressing a button.
The LCD switches from temperature to pressure at the touch of a button, with the display offering a choice of bar/C or PSI/F.
The high-resolution display means that dV-2 Cool can also be used for measuring leaks in vacuums.
The sensors with electronics are tested in test benches over pressure and temperature and then mounted into the housings.
The media contact parts are stainless steel, the mounting of the sensor into the housing is made by welding or with O-ring seals.
The sensor outlet is in the rear or the bottom of the housing.
