Meriam Instrument's 2100 Smart Gauges are micro-
processor based pressure sensing devices that can
be used to measure pressure, differential pressure
(air or gas flow), or hydrostatic level. There are
three models in the series: the 2110Pis principally
for pressure measurements, the 2110Lis for level
measure and the 2110F is for gas flow measurement.
These three units share the same hardware, but have
different software programs based on the function.
Meriam Instrument's 21l0PSmart Gauge is a microprocessor based, programmable, pressure sensing device.
The ranges available allow for measurement of pressure, differential pressure, vacuum and absolute pressure.
All units are programmed to allow easy configuration of the gauge through the front keypad. The AC powered
and 4 to 20 mA units can also be configured through the RS-232C serial communications port.
The SPDT relays on the AC powered models are an ideal choice for process control functions. The 4 to 20 mA
outputs on the 24 Vdc model allows the 2110Pto be used in both control and recording applications. Both
models also have RS-232C communications for high level control and data logging capabilities. Typical appli-
cations include use as a test bench gauge, tank level measurement, gas flow measurement and leak testing.
Pressure Switch In this application the 2100 has two distinct advantages over mechanical gauges. First, the
actual switching point can be precisely set. Auser can "see" the set point without having to make trial and
error adjustments. Second, it reduces excessive dead band or hysteresis ñ a common complaint about mechanical
gauges. The dead band in the 2100 is user selectable for exact control.
Absolute / Vacuum Measurement Absolute models give resolution to 0.1 mm Hg. Vacuum units have 0.001"
Hg resolution over the entire vacuum range. The combination of resolution, 0.05% of full scale accuracy, out-
puts and low price make the 2100 a good choice for customers in research and development laboratories and
process measurement.
