Bridge / Transducer Amplifier

FE-(H)389-TA

The latest in a line of transducer amplifiers providing features demanded by our customer’s experiences of decades of D.C. bridge applications. 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).

Vibration

FE-294-IA Integrator module

Integrator module used to provide velocity and displacement measurements to complement an acceleration measurement.

Acceleration

Charge Amplifier FE-128-CA

High performance charge amplifier with calibrated controls, covering the range 1pC to 50,000pC and developing ± 10V output. The amplifier has good L.F. response and quasi-static performance with high frequency response up to 100 kHz. A range switch and calibrated ten turn dial match the unit to the transducer sensitivity. A separate switch allows the number of mechanical units per volt of output to be set. The module’s low pass filter cut off frequency is easily changed using a plug in resistor pack. . A compatible wide range integrator is available – see FE-294-IA.

Charge Amplifier FE-128-CA-H

This module is similar to the standard FE-128-CA but converts higher charge signals (up to 500,000 pC for ±10V output.)

FE-071-HA/C IEPE Head Amp for Low Source Resistance Source

A series of in line head amplifiers which can be used when Charge Transducers have low impedance due to elevated temperature.

FE-074-HA/C Compact Head Amplifiers for Charge Accelerometers

The FE-074-HA/C is a charge amplifier for application as a head amplifier in IEPE type systems using nominally 2-4 mA. Versions are avaialble with a sensitivity of either 1mV/pC or 10 mV/pC. The unit transmits AC signals on coaxial cable and is compatible with IEPE sources of 2-6 mA. The frequency response extends from approximately 1 Hz to 25 kHz with a dynamic range extending up to 2V RMS. Connection is BNC or microdot input and BNC output.

Differential Charge Head Amplifier FE-077-DCA

The FE-077-DCA is intended for use with double ended (differential) accelerometers typically used for machine vibration monitoring. This is an ICP device powered by a current in a coaxial cable which also carries the signal to the receiver amplifier. For a compatible receiver amplifier, see the FE-530-IE.

Capacitance

Capacitance Displacement Amplifier FE-419-CDT

Designed for measurements up to 1 kHz in high temperature environments where long cables (coax or triax) are often necessary. The FE-419-CDT overcomes the difficulties of operating guarded capacitive sensors to measure clearances in applications such as turbines. The output is proportional to distance from the target and standard modules operate with transducers with target capacitance ranging from 2.5 pF down to 0.025 pF

Capacitance Displacement Amplifier FE-420-CD

This module differs from the FE-419-CDT in giving greater sensitivity at the expense of reduced tolerance of cable capacitance. (2 m cable lengths are recommended.) Measurement distance depends mainly on the transducer type and can range from microns to centimetres. It is suited to applications involving extremely small distance variations and fast rise times.

Other

Differential D.C. Amplifier FE-351-UA

Offering very low noise and drift performance, this differential d.c. pre-amplifier has a gain range from x0.2 to x10,000 (±0.1%) using switched attenuator and switched and vernier gain controls. Offset and calibration controls are provided. An on board auxiliary socket can accept a plug in 4 pole low pass filter. A front panel LED illuminates when fitted.

16 Channel Digital Monitor FE-M16-DS

A 16-channel digital monitor, the M16-DS is ideal for use in any FYLDE enclosure where it will monitor and display the outputs from each installed module. It provides a switchable selection for 16 differential inputs or 32 single ended inputs. The monitor will also measure A.C. with its built in precision rectifier scaled for RMS. A peak hold function completes the display options for time varying signals. A front panel BNC socket enables additional monitoring equipment to be connected.
