Gas Sensors

Toxic Gas Sensor This toxic gas sensor responds to a large number of airborne toxic compounds. It is designed to operate with a stabilized 5V heater supply and a circuit voltage not exceeding 24V. Its most suitable application is for a gas leak alarm or automatic ventilator control. The initial stabilization time is very short and the relative and elapsed characteristics are very good over a long period of time. It also has a very low sensitivity to "noise gasses" which considerably reduces the problem of false alarming.

Flex Sensor

Flex Sensor The Flex Sensor is a unique component that changes resistance when bent. An unflexed sensor has a nominal resistance of 10,000 ohms (10 K). As the flex sensor is bent the resistance gradually increases. When the sensor is bent at 90 degrees its resistance will range between 30-40 K ohms.

Available in three resistance ranges:

  • FLX-01-L Low resistance range, nominal resistance between 1K - 20K
  • FLX-01-M Medium resistance range, nominal resistance between 20K - 50K
  • FLX-01-H High resistance range, nominal resistance between 50K - 200K

Flexiforce Pressure Sensors

Fleixiforce Sensor

These sensors are ideal for measuring forces without disturbing the dynamics of a test. They can be used to measure both static and dynamic forces. They are thin enough to enable non-intrusive measurement. The resistance of the sensor decreases as force is applied.

Force Sensing Resistors

Force Sensing Resistors Force Sensing Resistors (FSR) are a polymer thick film (PTF) device which exhibits a decrease in resistance with an increase in the force applied to the active surface. Its force sensitivity is optimized for use in human touch control of electronic devices. FSRs are not a load cell or strain gauge, though they have similar properties. FSRs are not suitable for precision measurements.

For more information about these Force Sensing Resistors read the FSR Guide PDF.

Digital Compass

1490 Digital compass The 1490 Digital Compass is a solid state device capable of detecting the earth's weak magnetic field. It can distinguish between the four cardinal points and also the intermediate directions (NE, NW, SE, SW). The sensor is dampened to approximate the speed of a liquid filled compass.

Analog Compass

1490 Digital compass The 1525 Analog compass measures the direction of the horizontal component of the earths field. For practical purposes up to a 12 degree tilt, as with any compass is acceptable. The output closely resembles a sine-cosine set of curves.

Tilt Switch

mercury tilt switch Tilt switches, available in five and four pin configurations (metal ball in can) and three pin mercury.

The differential angle is approximately 15 degrees +/- 5 degrees depending on the speed and smoothness of the tilt. The slower the speed and smoother the tilt the greater the differential angle.
