FE-316-DYN

Micro Analog 2 – DYNAMIC STRAIN GAUGE AMPLIFIER

The FE-316-DYN is a dual channel dynamic strain gauge amplifier which energises a gauge or bridge using a unique low noise balanced dynamic constant current.

The unit is presented as a printed circuit card with jumpers which select constant current, gain and filter bypass.

Filter settings are by plug-in resistor network:

The 8 pole (-48 dB / octave) LP
The 2 pole (-12 dB / Octave) HP

The constant current supply is very low noise and is balanced so that the load resistance develops approximately equal positive and negative voltages at its terminals.

Card Size, FYLDE MicroAnalog2 Format:

180 mm x 67 mm

FE-(H)389-TA

BLUE PANEL SERIES – SMART TRANSDUCER AMPLIFIER

The FE-(H)389-TA is a high performance DC Bridge / Transducer Amplifier replacing both the FE-379-TA & FE-H379-TA amplifiers and is available in two versions.

The standard FE-389-TA has a bandwidth of >1MHz and gains from x10 to x5000. The standard version is hardware upgradable to the FE-(H)389-TA version.

This provides an increased gain range (x5 to x10000) and a SMART Input Stage that automatically configures itself to provide the lowest noise or highest bandwidth (>2MHz) depending on the Front Panel settings.

Because of the SMART Input Stage the output noise of the FE-(H)389-TA with a >2MHz bandwidth is substantially lower than that of the FE-H379-TA (bandwidth 500kHz).

Low Frequency (L.F. or 1/F) noise has also been substantially lowered.

Six Front Panel push buttons and a single rotary controller allow for simple adjustment of all functions.

A ring of 19 multi-colour LEDs around the controller are
used to indicate all the function states.

Once set up is complete, all controls can be locked to help avoid inadvertant changes to settings.

It is suitable for use with DC bridge type transducers and complete or fractional strain gauge bridges. Because of its high bandwidth (>2MHz), the FE-(H)389-TA is highly recommended for Hopkinson Bar type measurements.

The module is powered from 10V to 36V DC. This allows it to be used directly in automotive envionments or it can be mains powered via standard mains adaptors.

Housings are available for individual modules or for multi-channel systems.

FE-390-IF

BLUE PANEL SERIES – INTERFACE

The FE-390-IF is a compact module that provides remote control of compatible Fylde modules.
The unit connects to the rear of racks fitted with remote enabled 15-way D connectors and is powered by the rack. A 2nd D connector (9-way) provides a standard RS232 link to a PC. ASCII commands sent from a terminal program such as Hyperterminal or RealTerm set the parameters of individual or multiple modules in the rack. Settings can also be retrieved and viewed remotely from modules.

A Windows based LabView program is available to provide a graphical control interface. This is currently for racks fitted with FE-389-TA modules with potential future versions including more module types.

Compatible modules and remote functions available.
1. FE-389-TA Gain: bridge volts, filter, panel lock, auto-zero, auto-balance, calibration setting. 2. FE-530-IE: Gain, current setting, filter setting.
