Macro Sensors Broadens Line of Economical, User-Friendly LVDT Signal Conditioners with 4-20mA Output Model

LVDT signal conditioners offer easy calibration and low price point to save time and money

Pennsauken, NJ, April 18, 2011…

Macro Sensors broadens its EAZY-CAL™ MMX Series of Mini-Module LVDT Signal Conditioners with a 4-20mA output model that supports process control and factory automation applications often requiring longer cable runs. This user-friendly, single channel signal conditioner is also available with a low noise 0-10V DC output.

To reduce noise and to eliminate voltage drops in analog voltage signals, the market place has adopted an analog current (4-20mA) output as its standard. A 4-20mA current output allows the user to run longer cables from the sensor to the control system without the worry of noise being induced on the signal or having to calibrate out the voltage drop due to the impedance of the cabling.

EAZY-CAL Mini-Module LVDT Signal Conditioners (http://www.macrosensors.com/MMX_series.html) are quickly calibrated in mere seconds using two front panel push buttons. The elimination of repetitive null and span potentiometer adjustments associated with conventional analog based signal conditioners enables a faster and easier set up. An intuitive, sequencing four LED status indicator guides an operator through the calibration process, and provides foolproof feedback to insure calibration integrity.

In addition to a simplistic calibration, the EAZY-CAL Mini-Module LVDT Signal Conditioners measure just 2.77” x 3.35” x 0.7”, taking up less space than standard size, din rail signal conditioners. Compact and lightweight, modules are ideal for installation in locations with limited space.

The EAZY-CAL MMX Series of Mini-Module LVDT Signal Conditioners are also economically priced for the OEM market. Modules support most manufacturers’ LVDT position sensors with plug and play compatibility and can be remotely located by up to 100+ feet to facilitate LVDT operation in extreme environments.

For multiple channel applications, up to 10 EAZYCAL ™ MMX Series modules can be connected together in master/slave mode to synchronize their excitation oscillator frequency, eliminating effects of heterodyning and spurious beat frequency signals, cross talk, and intermodulation effects.
