These transducers are designed for general use in data acquisition and recording instruments and systems. They are supplied with 5-ft cables terminating in an 8-pin DIN connector which readily plugs into Transbridge, a 4-channel analog signal conditioner and Bridge/8. Transducers can be easily converted with adapter cables and plugs to work with most standard recording systems and polygraphic instruments.

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. Fiber optic cables up to 2 mm diameter may be inserted into the tip. |

FORT TRANSDUCER
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.

|
| This 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. |

BLPR2 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.) |
