FOR-1 Single-Channel Data Acquisition Unit

COMPACT SINGLE CHANNEL READOUT

PRESSURE, TEMPERATURE, STRAIN & DISPLACEMENT

RUGGED & EASY TO USE

The FOR-1 is a single-channel, battery-powered fiber Optic readout able to measure pressure, temperature, strain and displacement sensors with great accuracy

Description

Fiber optic temperature, pressure, strain and displacement transducers feature complete immunity to microwave and RF radiation with high temperature operating capability, intrinsic safety and non-invasive use. A 7-digit gauge factor affixed on the connector of each transducer allows the FOR-1 readout to easily recognize the transducer type and calibration.

Through the use of a white-light cross-correlator (U.S. Patents 5,392,117 and 5,202,939), the FOR-1 is capable of measuring with astonishing accuracy the absolute cavity length of Fabry-Perot fiber optic transducers, providing time-after-time consistency in the most adverse conditions. The FOR-1 has a 0.01% F.S. resolution (without averaging) and 0.025% F.S. precision.

The FOR-1 readout has a non-volatile memory buffer that can store up to 50 000 data samples. Datalogging sequences, duration and other operational parameters are easily programmable using the front panel interface or through the RS-232 communication port. The FOR-1 comes standard with an RS-232 communication port and a ±10 V adjustable analog output.

The use of a flash EEPROM allows for easy firmware upgrade.

The FOR-1 comes in a rugged 1/8 DIN casing designed to withstand heavy use and operation in industrial environments and has up to 8 hours of battery life.
