Temperature

An integrated-circuit temperature sensor, CELS monitors temperature at the probe tip and produces 10 millivolts per degree Celsius when powered by a source of +5 volts or more and a -5 volts or more with respect to the transducer's ground terminal. Stainless steel probe with epoxy tip.

Light

When powered by +2 volts or more, LUME provides an output voltage signal proportional to incident light over the visible to near infra red spectrum. Containing a miniature silicon photodiode, the slender stainless steel probe can be easily mounted to do a wide variety of useful jobs, such as monitoring transmitted, reflected or interrupted light beams. Fibre optic cables up to 2 mm diameter may be inserted into the tip.

Pressure

PNEU transducers are accurate differential pressure measuring devices for non-corrosive gases and liquids. Linear and repeatable, with little temperature drift, they convert hydrostatic pressure levels to stable and proportional voltage signals.

Displacement

Model DSPL smoothly converts mechanical displacement into a proportional voltage with virtually infinite resolution and essentially zero frictional drag. Based on the Hall effect, which uses a magnetic sensor.

Force

These rigid-lever force transducers transform applied force into proportional voltage. Using balanced strain gauges, FORT transducers produce linear output voltage vs. applied force input with very little deflection. To use, clamp the handle of the FORT transducer in a horizontal position and apply the forces to be measured to a rivet or hook mounted in the hole at the end of the flat sensing leaf.

The 25-gram force transducer is a reliable tool for high precision force measurement. Using balanced semiconductor strain gauges, FORT25 produces linear output voltage vs. applied force input with very little deflection. The rigid lever force transducer transforms the applied force into a proportional voltage. It is a temperature-compensated full-bridge configuration with four high sensitivity semiconductor strain gauges. FORT25 has a broad dynamic measuring range and a very high sensitivity. To use, clamp the handle of the FORT25 transducer in a horizontal position and apply the forces to be measured to a rivet or hook mounted in the hole at the end of the flat sensing leaf.

Blood Pressure

BLPR2 can be used for the direct arterial and venous pressure measurement in animal blood vessels. Supplied non-sterile, BLPR2 is accurate, linear and stable with temperature. May be sterilized cold with Cidex or a similar bactericide. BLPR2 is equipped with a twelve-foot cable and connector compatible with WPI's four-channel signal conditioning unit, TBM-4M Transbridge, and the single-channel BP-1 blood pressure monitor. Cable has moisture-resistant locking connector. A continuous, uniform lumen eliminates places for bubbles to form and lodge. The clear fluid path is easy to inspect. To facilitate setup and operation, a four-way stopcock that allows easy filling, flushing, and zeroing of the transducer is included. Typically, the stopcock is located between the transducer and the animal catheter where it can be used to quickly zero, flush, or de-bubble the transducer. This new unit come with an internal gain resistor specifically for the LabTrax 4-24T (all other WPI amplifiers are unaffected by this addition.)
