Description
The M-35 Microminiature Process Meter is the solution when
panel space is limited or the size and weight of the indicator must
be as small as possible. The bezel measures only 24 x 48 mm
(0.94" x 1.89"), yet the height of the red LED digits is a full 10 mm
(0.4").
The M-35 is a scaleable 3-1/2 digit process meter for 4-20 mA,
0-10 mA, 0-2 V, 1-5 V, and 0-10 V signals. It is powered from
10-30 Vdc, so that it can run off batteries. Power and signal are
isolated to facilitate panel design, with no worries about ground
loop errors.
A detachable screw terminal con-
nector is standard and provides a
benefit rarely found on meters of this
size. The connector pin assignments
as well as the zero and span adjust-
ments are clearly labeled on the back
of the meter.
This diagram for a typical pressure monitoring application shows
how simple the M-35 is to connect. The same DC source powers
the transducer and meter. Only three field wires are required.
Small size, low weight, and isolated DC power make the M-35
ideal for portable test equipment.
