Ruskin Model AMS810 is an accurate and economical solution for
measuring and reporting differential pressure when used in con-
junction with any Ruskin velocity pressure air measuring probe
(AMP series), air measuring station (AMS series) or air measuring
louver (AML series) product. The heart of the unit is a micro-
machined single-crystal silicon piezoresistive pressure sensor. The
sensor receives a five-point error correction over the compensated
temperature range for excellent accuracy, repeatability and stabil-
ity. The unit comes standard in an IP66-rated enclosure with short
circuit proof outputs and reverse polarity protected inputs to per-
form under real world conditions. The unit installs quickly by con-
necting standard 1/8" I.D. tubing to the two pressure ports. The vari-
ous Output Ranges and Pressure Ranges are all field selectable
with DIP switches, and the auto-zeroing process is microproces-
sor-controlled for simplicity.
THREE YEAR WARRANTY!
VARIATIONS
The AMS810 is available in a 0 to 1 Inch Water Column range for
higher resolution where velocities are 2,000 FPM or less.

Furnish and install, at locations shown on plans or as in accordance
with schedules, an air measuring station pressure transducer, with
integral LCD display indicating actual differential pressure. The trans-
ducer shall be housed in a polycarbonate enclosure that bears an IP66
rating. Enclosure shall have a hinged cover for access to all dip
switches for field adjustment. Dip switches shall allow for field selec-
tion of 0-5 VDC, 0-10 VDC or 4-20 mA output signal. Additionally, dip
switch settings shall accommodate field selection of a minimum of five
pressure ranges from 0" to 2.5" water column (0" to 1.0" optional). The
transducer shall have an auto-zero function that is microprocessor
controlled. The transducer assembly shall contain a micromachined,
single-crystal silicon, piezoresistive pressure sensor with strain gages
to change resistance as a function of applied pressure. Sensor shall
be paired with an application specific integrated circuit to digitally com-
pensate for thermal sensitivity. Accuracy of the transducer shall be
±.05% on 0 to 0.1" range and 0.25" range, ±0.25% on all other ranges.
Stability shall be ±0.25% (of span selected) per year. Transducer shall
be, in all respects, equivalent to Ruskin Model AMS810 and shall be
compatible with all Ruskin air measuring probes and stations.

PARAGRAPH SPECIFICATION
SELECTING PRESS RE RANGE
To adjust the pressure range, set dip switches 1-4 to the desired
pressure range using the label found inside the cover of the
AMS810 unit (or indicated to the left).*
SELECTING O T P T RANGE
To adjust the output range, set dip switches 5 & 6 to the desired
output range using the label found inside the cover of the AMS810
unit (or indicated to the left).
A TO-ZERO
To auto-zero the AMS810, remove the tubing from the pressure
ports. Use a small piece of tubing to connect the high and low side
together, if possible. Turn on dip switch 7 to start the process. The
LED light will blink fast and the output will be forced to zero (4mA
or 0 V). When LED light blinks slow, replace the tubes and turn dip
switch 7 back OFF as shown in detail to the left.
*Note: Optional 0-1.0 Inch Water Column ranges are 0.10, 0.25,
0.50, 0.75 and 1.00.
