Multi-Purpose Digital Manometers: dV-1 / dV-2 / dV-2 Cool
dV-1: Digital Manometer in Installation Housing or for Direct Mounting
KELLER has developed a new ASIC (Application Specific Integrated Circuit) especially for use in the dV-1 series manometers. The integration of analog and digital signals (Mixed Signal ASIC) has enabled the realisation of an extremely compact manometer with a digital display and very low power consumption. A resolution of 0,5 %FS (200 measuring points) and measuring interval of 250 ms makes it ideal for applications where a simple pressure value display is adequate.
dV-2: Digital Manometer for High Volume Applications
The dV-2 Series incorporates many of KELLER's latest developments in electronics to produce a simple low cost digital pressure gauge that is packed full of features normally found only on expensive instruments. The dV-2 can be set up to perform various measuring functions via two front panel operating buttons. Gauges are available in three accuracy classes: • 0,5 %FS (Standard) / • 0,2 %FS (Silver) / • 0,1 %FS (Gold)
dV-2 Cool: Digital Manometer for Coolant Examination
The dV-2 Cool was designed for monitoring tasks at coolant filling stations. Vapour pressure/temperature graphs for 5 coolant liquids are saved in the unit and 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.
