is a terminal strip on the back of the WR-100P panel mount gauge allowing for a
variety of relay outputs and for gauge power.
not all WR-100P units have control outputs. The option outputs available are SPDT,
250 VAC, 7 amps. The normally
open contacts or close them once the vacuum setpoint is reached.
atmosphere, the unit reads 760
Torr. A visible
decimal point indicates that the unit is reading in Torr.
As pressures are decreased toward full vacuum, the unit's readings
will shift to 99.0, 9.99,
and finally to 999 When
no decimal points are visible, the unit is reading in millitorr or microns
of mercury vacuum.
The WR-100P gauge comes
with two adjustable set-points.
Output is also available for
either model and can be supplied for external data logging. The output can
be seen on any computer with a serial port.
For example, any PC running Windows Terminal or Hyperterm will show
the output. For special applications, such as logging of data, HyVac
offers custom Visual Basic Applications which log data at selected
intervals, and provide a high resolution plot of the data on a black and
white or color printer.
special orders, analog outputs (for driving strip chart recorders and
similar equipment) are available.
the gauge is to be used in a neon sign processing facility, it must be
installed with a stopcock or a solenoid valve to protect it from exposure
to the system and possible damage during high voltage bombarding
