THIN FILM
Thin Film
Precision micro-deposited layers on stainless steel diaphragms. Ideal for pressure, force, load, weight and torque measurement.
ULTRASONIC
Ultrasonic
Sound-wave measurement through tube walls with zero intrusion. Used for flow, bubble detection and liquid level sensing.
CAPACITIVE
Capacitive
Non-invasive electric field sensing through vessel walls. Ideal for continuous and point liquid level detection without contact.
OPTICAL
Optical
Infrared light refraction through a prism tip for precise point-level sensing of water and other liquids. No moving parts, no calibration required.
PRECISION OEM SENSING
Engineered for the applications where failure is not an option
SMD Sensors designs and manufactures precision sensing solutions for medical devices, industrial automation, and life-critical equipment. Our OEM sensors are built to perform in environments where accuracy, reliability, and longevity are not negotiable.
From thin film pressure sensors rated to ±0.1% accuracy, to clamp-on ultrasonic flow and bubble detection sensors — every product is engineered, calibrated, and tested to exacting OEM specifications.
