MTM/N10 Miniature Depth and Level Pressure Sensor Brochure

 Submersible, 0.39“ diameter Fully isolated sensing element Accuracies of ±0.1%, ±0.25% or ±0.5% Ranges from 0 to 15 psi to 0 to 150 psi Gauge or absolute pressure Optional separate electronics foramplifi ed outputi.e. 4 to 20 mA, 0 to 5/10 VDCThe MTM/N10 depth and level pressure sensor is available for applications where space is very limited. The housing diameter of 0.39 inches offers the user an ideal high performance level measurement in small diameter, i.e. 1/2“ monitoring wells, stand pipes and bore holes. The stainless steel construction and integral polyurethane cable provide a reliable long term solution for these diffi cult-to-measure applications. Kevlar is used as a cable reinforcement to avoid any elongation, particularly when long lengths of cable are required for deep wells. Long term stability of typically ±0.1% per year also contributes toward a maintenance-free installation.STS also offers a range of 1“ diameter dataloggers which can be supplied in-line or at the well head for continuous monitoring.MINIATURE DEPTH ANDLEVEL PRESSURE SENSORMTM/N10- feel the Difference15Product overview and applicationsFeaturesProcess Measurement & Controls, Inc.
