FIBER OPTIC TEMPERATURE SYSTEM - FOTS100

Stand-alone Fiber Optic Temperature System

FOTS100 includes control unit with RS-232 port, ± 5 V analog output, and rubber boot; power via 9 V battery or wall power.

This is a stand alone system, but it can also be interfaced to BIOPAC MP Systems:

MP150 or MP100 System: add CBL101 (separate purchase).

MP36/35 System: add SS70L isolated BNC interface and a BNC-to-RCA cable (separate purchase)

The analog output parameters comprise the scale factor and the offset. The scale factor corresponds to the physical unit per Volt (unit/V) output by the system, while the offset corresponds to the physical value at which the user wants the analog output to be at zero volt. For example, with a scale factor set to 10 °C / V and the offset set to 5 °C, the temperature as a function of the analog output voltage is given by:

Temperature = [Voltage output] x 10 °C / V + 5 °C

The default value of the scale factor is 50 °C / V (or its equivalent in °F) and the default value of the offset is 0 °C (or its equivalent in °F).

During a No Signal condition, constant values are output as follows: analog output value = 0 Volt, RS-232 serial ports = 65 536.0.

For more details, please see the complete FOTS100 User Manual, available under the Resource tab below.

Use with high-accuracy, MRI-compatible fiber optic temperature probes (separate purchase):

TSD180 Rectal Temp Probe: 300 µm OD Polyimide tubing, 8 m

The Polyimide round tubing protects the sensing element its flexibility and rigidity provide excellent pushability.

TSD181 Surface Temp Probe: sensor 1 mm OD, PFA tubing 0.9 mm OD, 8 m

cable sheath rated up to 85 °C.

The glass tube at the end of the probe provides a robust protection over the sensing element as well as a firm connection from sensor to cable.
