HNL INSTRUMENTS & CONTROLS
700 Series Range
Selection
The tables below detail the Series 700
Pressure and Differential Pressure (DP) ranges available.
For each Range Code the range of adjustment of the switching point is
given from MIN to MAX together with the units of measurement. E.g.
The setpoint adjustment for a 744P is from 0.1 to 1.4 bar.
The % RESET figure (or switching differential) is the difference in
pressure that must be applied to change the output switch state from
ON to OFF (or OFF to ON), and is expressed a percentage of the switch
range.
There are three standard diaphragm material options 1 - nitrile, 2 -
PTFE and 7 - hastelloy C. Availability of a given diaphragm material
for a selected range is indicated by a *, a blank indicates the
diaphragm material is not available.
There are three standard process chamber material options 1 -
aluminium, 5 - 316 stainless steel and 7 - hastelloy C. Availability
of a given chamber material is indicated by a number in the
appropriate column for a selected range. This number is the chamber
proof pressure rating in bar. A blank would indicate that the chamber
material is not available, a # indicates that availability must be
checked.
