Schroeder Industries MS12LC Differential Pressure Switch

Schroeder Industries MS12LC Differential Pressure Switch is a low‑current electrical differential pressure indicator designed to monitor pressure differences across filters and lines in hydraulic and lubrication systems. Part of Schroeder’s MS12 family, the MS12LC variant provides two 1/4" NPTF inlet/outlet test ports for easy installation and testing, and it is configured for a 27 psi differential setpoint in this model (MS12LC series also includes other setpoints, such as 30 psi). This DP switch supports multiple supply voltages (AC 120 V, AC 220 V, AC 24 V, AC 12 V and DC 110 V, DC 24 V, DC 12 V) and uses Buna seals, making it compatible with a wide range of industrial environments. It is intended for use on Schroeder pressure, return‑line, and medium‑pressure filters and is suitable for systems with working pressures up to 5000 psi (345 bar) and cyclic conditions up to 4000 psi (276 bar), enabling early alarm signaling when differential pressure indicates filter loading or flow restriction. Ideal for applications in filtration monitoring, hydraulic circuits, and lubrication systems where a reliable electrical switch is triggered by specific differential pressure, the MS12LC provides a durable, industry‑standard solution for 27 psi setpoint monitoring across Schroeder’s DP indicator lineup.
