| Connection
Example |
| The 88-Pro may be
connected to a wide range of signal loops, without additional
auxiliary or loop excitation power supplies, because the meter
is self powered and drops only 2.5V in the loop.

The simple example
shown could be used for measuring the contents of a straight
sided liquid storage tank. The transmitter would be sited near
the bottom of the tank, and as liquid level rises, so the
pressure at the base would rise. The meter's broad scaling
capabilities allow it to be adjusted to read in true volume.

The
88-Pro displays a wide range of process variables such as
temperature, pressure, flow, weight, pH, humidity, etc. It
accepts most process signals, such as 4-20mA and 1-5mA, and
gives superb value for money. |
| · |
The loop
voltage drop is only 2.5V |

The
simple bezel will compliment your panel design. The lens
protects all legends and markings, so repeated wipe-downs
won't damage the lettering or display clarity. High contrast
LCDs make these meters suitable for use in bright
environments. |
| · |
You can
extend the maximum reading up to 19990 or 199900 with fixed
zeros, selected by jumper switches. This is useful when the
cost of a 4 1/2 or 5 1/2 digit meter may be too high. |
| · |
There's
also an INVERT facility, so an increasing input signal gives a
reducing display, for example 4-20mA=100.0 to 0.0. |
| · |
The case
depth is less than that of our other process meters, saving
you valuable space in the panel.

| The
design of the connectors means that no extra depth is required
for cable loops. The cable exits the bottom surface of the
connector, not the rear. |
