Precision Scales
±0.05% accuracy including non-linearity, non-repeatability, and drift. Capacities from 0.1 to 1,000 lbs. Custom electronics, splash resistance, and RF immunity options.
Float Switches & Liquid Level Sensors
Vertical, horizontal, multi-level, and submersible float switches in stainless steel and plastics. OEM quantities. Custom molded designs in any material.
Optical Liquid Level Sensors
Switched output presence/absence sensing up to 250 PSIG. Six OS-series models with glass, industrial, and digital options.
Capacitive Level Sensors
Detects liquid presence through thin-wall non-conductive vessels using dielectric differences between air and liquid. Point and continuous measurement options.
Signal Conditioning
SMD engineering team designs fully integrated sensor solutions — filtering, averaging, temperature compensation, and calibration. Analog and digital protocols available.
Custom Solutions
30+ years of application-specific sensor design. SMD engineers produce custom miniature load cells, pressure sensors, and assemblies within tight time frames and aggressive cost targets.
