Transmitters
Process signal transmitters are discrete modules used to convert sensor or process input signals to a standard high-level output signal. . Models accept millivolt (mV), RTD, TC, strain gauge potentiometer, pulse/frequency AC, DC and provide standardized outputs like 4-20 ma or 0-10 VDC. Power AC or DC.

Two wire transmitter                                  
Series 100 two-wire transmitters provide a  cost effective means of solving local or remote signal conditioning applications. They convert most sensor inputs to provide a standard 4 to 20 ma dc output.

Alarm Module
Provide a relay contact output in response to either a sensor or process signal input reaching a preset trip/alarm level. Models accept millivolt (mV), RTD, TC, potentiometer, pulse/frequency, AC, DC and more. SPDT or DPDT 10 Amp.250V contact outputs. Adjustable setpoint, 
deadband and time delay.

Signal Isolators
Signal isolators break the direct electrical (galvanic) path between two or more loop points. They eliminate process signal ground loops, provide operator safety from hazardous voltages and increased protection from surges and spikes.

Two and three wire DIN Transmitters
Process single transmitter for AC voltage current, millivolts, frequency, potentiometer, RTD and Thermocouple DIN railmount.

Loop Power Supplies
Loop Power Supplies are primarily used to provide 24 VDC isolated power to process loops. Power up several Adtech 100 200 or 300 series two-Wire transmitters, operate from 115/230 VAC.

   Computation Module
  A reliable module for small systems requiring a 
  computation. We offer 3 groups defined as: Process
  Function, Math Function, Ramp Function. A few of
  the functions are:
  - Sample and Hold
  - Most process and arithmetic functions
    (adder/subtractor, multiplier/divider)
  - Ratio and Bias
  - Pulse integration summing and accumulation
  - Linearization

Indicators
Loop indicators provide local or remote indication of a process variable and are typically scaled to display engineering units. Operate from the input 4-20 mA loop power. Provide large 0.5" LCD display in a Nema 4 or 7 enclosure.

SGT-90
The Adtech model SGT-90 Strain Gauge Transmitter provides an accurate and economical way to convert a wide variety of primary element strain gauge transducers to a standard process current or voltage signal output. Excitation power for the bridge is provided by the transmitter as a standard feature and may be precisely controlled by a potentiometer. Recalibration to other desired ranges is accomplished easily with the use of a zero and span potentiometer located at the front of the unit. Power 115Vac or 24 Vdc.
