The Adtech Model ALM 00 Analog Linearizer Module offers an accurate and economical means of converting whole or fractional power functions into linear outputs such as linear flow outputs from flumes and weirs. It provides standard process current or voltage signals on the output with a maximum of 10mV P/P output ripple.

The standard model handles monotonic functions such as root extraction and power functions.

The Adtech Model ALM-00-042 Analog Linearizer Module (see picture for ALM 00) offers an accurate and economical means of converting whole or fractional power functions into linear outputs such as linear flow outputs from flumes and weirs. It provides a standard process current or voltage signal output with a maximum of 10mV P/P output ripple.

10-segment breakpoint linearizer, Option O42, provides easy calibration with each segment allowing an increase or decrease of slope with the center position of the potentiometer providing a gain of one.

The Adtech Model ALM-00-O43 Analog Linearizer Module (see picture for ALM 00) offers an accurate and economical means of converting whole or fractional power functions into linear outputs such as linear flow outputs from flumes and weirs. It provides a standard process current or voltage signal output with a maximum of 10 mV P/P output ripple.

Option O43 provides logarithmic functions on a continuous calculation method and the output may be the log of input or antilog of input.

The Adtech Model ASM 54 Adder Subtractor Module provides an accurate and economical means of adding and/or subtracting up to four process signal inputs to provide a standard process current or voltage signal output with a maximum of 10 mV P/P output ripple that represents the sum and/or difference of the inputs.

An exclusive feature eliminates the need to change any internal components or wiring when converting any of the four inputs from an adding or subtracting mode.

The ASM offers a convenient way of interfacing the sum or difference of signals to a computer system or other process instrumentation.

The Adtech Model MDB 52 Analog Multiplier/Divider Module accepts up to three (3) process signal inputs and performs one of the following computations: multiply/divide, multiply, divide, square root and the square root of ratio or product. An exclusive output option (O44) provides a pulse rate output along with the standard analog output.

The MDB 52 provides standard process current or voltage signals on the output with a maximum of 10 mV P/P output ripple. Recalibration to other desired ranges is accomplished easily.

The Adtech Model PSM 57 Pulse Summing Module ( MDB 52 for picture) provides an accurate and economical means of adding (summing or counting up) multiple contact closure or pulse rate inputs to a single output pulse rate representing the sum of the inputs. The PSM 57 may also be configured to subtract multiple inputs.

The PSM 57 is supplied with three of the four inputs "A, B and C", each set up for two decades of scaling per input as standard with no scaling for input "D". The minimum "discrimination time" between input pulses is 0.01 milliseconds.

The Adtech Model SCX 102 Loop Powered Isolator/Repeater provides a solution for ground loops and problems encountered in connecting together recorders, process control systems and computers.

The SCX 102 accepts a 4-20 mA signal and provides an isolated 4-20 mA output. Operating power is derived from the input signal so no external power source is required.

DIN mounting is supplied as standard. Surface mount (Option H26) or snap track mount (Option H25) are available at no extra cost (specify).
