Sensor signal conditioner has all the answers
- and displays them too!
RDP Electronics E725 is the control hub of any
stand-alone measurement system. Combining an
all-in-one conditioning unit for a wide variety of
LVDTs, and most strain gauge sensors, with local
data display and network data transmission, the
compact E725 provides the power and signal
conditioning for the transducer, interprets the
resulting signal and presents the results on its
clear LED display.
E725 conditioner units are available for a variety of transducer
styles and with a range of features and options including trip
switch outputs. In addition to the standard TTL outputs, options
are available for solid state or mechanical relay contacts in
regular or fast-acting versions. The E725 may be fitted with
a range of input boards including AC for LVDT or half-bridge
inductive sensors and DC for strain gauge and amplified
For measurement systems which require several independent
transducer outputs to be monitored and controlled centrally in
a cost-effective way, the answer is a E725 network. The E725
offers an optional RS485 output with up to 256 units supported
on the same network. The integral microprocessor provides
the calculation power, linearisation options and data management
and a PC may be used either with the RS232 direct connection
(for a single E725) or via an RS485 to RS232 converter from a
network. The PC provides the means to control the E725s
centrally and by installing the free RDP software (downloadable
from the website) the PC can be used to capture, analyse and
display the data too.
Front panel control functions may be remotely controlled by
applying a DC voltage to the digital input connector. Functions
including zeroing the display, changing the display mode and
freezing the display are all available remotely using this connection.
The E725 can be supplied from a variety of AC and DC supplies:
5V, 12V and 24VDC and 105V, 115V and 230VAC and it
provides both 4-20mA and 0-10V analogue outputs.
