EM certified (CE Mark).
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 fully 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 connector provides a benefit rarely found on meters of this size. Small size, low weight, and isolated DC power make the M-35 ideal for portable test equipment.
The above diagram for a typical pressure
monitoring / manometer 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. |

A removable screw terminal is standard. The connector pin assignments as well as the zero and span adjustments are clearly labeled on the back of the meter. |
