Strain Measurement Devices (SMD) provides a wide variety of strain gauge load cell solutions, including miniature, micro and low-force load cells.
Strain Measurement Devices (SMD) manufactures monitoring solutions for medical devices.
The company’s speciality sensors are designed to measure a wide variety of characteristics, including load, force, pressure, air and gas bubbles in tubing, liquid levels, flow rates and occlusion.
SMD also designs customised low-profile weight scales.

Load cell and force sensor manufacturing for medical devices
SMD designs and manufactures strain gage load cells and force sensors using an integrated design process to meet client expectations.
The company utilises a sputtered thin-film process in strain gage circuit production, which involves the sputter deposition of thin films of dielectric and resistor alloy onto metal components. This process forms a molecular bond with the component and avoids the use of adhesives and associated errors.
SMD’s strain gauges are precisely configured using state-of-the-art laser-trimming technologies, which allows the strain gage circuit to be placed on a small surface area and enables clients to reduce the design footprint of their medical devices.
Bubble and occlusion sensors for fluid management systems
SMD manufactures accurate bubble and occlusion sensors for tubing and flow meters.
These are used in fluid management systems such as medical intravenous (IV) and syringe pumps, urology diagnosis machines, clinical chemistry and immune assay diagnostic machines.
The bubble sensors use high-quality ultrasonic technology to detect bubbles as small as 1µl using signal conditioning and dry coupling.
The occlusion sensors use thin-film load sensor technology to detect changes in pressure caused when tubes are blocked. This non-invasive solution is used to test whether valve manifolds are positioned correctly.
Flow rate management and fluid detection in medical devices
SMD’s flow and fluid management solutions provide accurate monitoring of flow rate and flow volume, as well as fluid type.
The ultrasonic flow sensors are available as clamp-on or flow-in configurations to collect flow rate data, totalised flow volume, signal strength and average speed-of-sound of a fluid. Speed-of-sound data can be used to detect and differentiate between liquids.
The FlowDAQ detects and manages flow rate and collected data can be used as feedback.
Weight scales for liquid volume measurements
SMD offers hanging scale sensors designed for intravenous (IV) bags. These scales can precisely measure weights from 0.4kg to 50kg.
A low-profile stainless-steel weight scale unit is also available with applications in cylinder weight monitoring in semiconductor critical gas distribution systems.
Two-part assembly pressure sensor
SMD’s small-diameter tubing pressure sensor consists of two parts assembled together. One part is a low-cost disposable flow module, while the other is a reusable pressure sensor.
The sensor can be used to detect pressure in tubing up to 0.25in in diameter.
SMD provides monitoring solutions to markets in the US and Europe. The company has offices in Wallingford, Connecticut, US, and Chedburgh, UK.
Strain Measurement Device's (SMD) standard bubble sensors can detect bubbles as small as 0.1 microliters, but its SMD engineers can create custom bubble detector solutions for any application.
Strain Measurement Devices (SMD) is a speciality sensor designer, established in 1979. It is devoted to exclusively creating and manufacturing custom and standard sensors, supplying leading-edge technology offering superior stability, temperature performance, design flexibility and low-power consumption.
Hanging scales are commonly used for weighing materials suspended in the air in a variety of applications and in many markets, such as agricultural and industrial sectors, where uses involve attaching a bag or container onto the hanging scale hook.
Strain Measurement Devices offers a number of load cell force sensors that measure ranges from 10g to 455Kg (1,000lb).
Strain Measurement Devices (SMD) has been hard at work engineering and designing new disposable sensors for each product line, offering contamination free and inexpensive, one-time use sensors to help you with the monitoring in your application.
