PMC-STS, Inc.

PMC-STS, Inc. is a Danbury, Connecticut-based manufacturer of precision sensing instrumentation, founded in 1963 and recognized for its patented flush sensor technology. All products are designed and manufactured in the United States, with custom engineering available alongside catalog offerings. For water and wastewater applications, PMC-STS provides a broad submersible depth and level transmitter portfolio: the VersaLine Series for general-purpose measurements, the VL2000 rated specifically for wastewater environments, a miniature 0.39-inch diameter submersible for confined installations, combination level-and-temperature submersibles, chemical-resistant variants, rangeable and programmable models, STS Series transmitters in millivolt, voltage, and current outputs, Smart HART Protocol versions, precision SDI-12 units, and topside pressure transmitters. Their precision pressure line includes 4–20 mA current output models (STS ATM.1ST), voltage output transmitters, intrinsically safe process transmitters, subsea-rated pressure transmitters, combination pressure-and-temperature units, CANbus/RS485 digital output models, Tri-Clamp open face flush transmitters, PT miniature transmitters, and OEM piezoresistive pressure transducers. The flush-mount family—PMC’s signature technology—spans analog electronic and miniature transmitters, seal gauges and switches, pneumatic miniature variants, and Smart HART Protocol versions. Differential pressure offerings center on the DP2000 Series, with current output, aerodynamic, high-line, and low-pressure wet/dry configurations. The PZ770 Series serves on-vehicle test and measurement. PMC-STS serves water and wastewater, aerospace, motorsport, pulp and paper, and oil and gas industries.
