The Pirani Gauge head filament has high temperature co-efficient of resistance. So a slight change in system pressure brings about useful change in filament resistance resulting in an out of balance voltage which can be read as a pressure on meter. The Pirani Gauge head...
The Digital Pirani Vaccum Gauge helps the user to measure small pressure changes. In a Digital Pirani Vacuum Gauge, nickel and tungsten wires are used as filament. Nickel Wire does not only have higher sensitivity but also possess other advantages....
We offer high quality Digital Penning Vacuum Gauge . Digital Penning Vacuum Gauge is a Cathode Ionised Gauge that consists of two electrodes: anode and cathode. When difference of 2.2 KV passes between the anode and cathode through the resistors, a...
Analog Penning Vacuum Gauge is a cold cathode ionization Gauge that consist of two electrode cathodes. In the Analog Penning Vacuum Gauge a difference of about 2.2KV is applied between the anode and the cathode through current limiting resistor. The...
The Pirani gauge consists of a metal filament (usually platinum) suspended in a tube which is connected to the system whose vacuum is to be measured. Connection is usually made either by a ground glass joint or a flanged metal connector, sealed with...
A special form of the Pirani gauge is the pulsed Pirani vacuum gauge where the filament is not operated at a constant temperature, but is cyclically heated up to a certain temperature threshold by an increasing voltage ramp. ... The required heat-up...
