# Multipliers

We offer a number of instruments for carrying out Mathematical functions on high level signals.

Function: The instruments consist of a multi-functional analogue computing circuit which is factory calibrated as either a divider, multiplier, squarer, square root extractor or rectangular weir lineariser.  If the measured process variable is temperature dependent, such as flow for instance, then the instrument can also be factory calibrated to accept a temperature compensation input for mass flow computation.

Operational notes: The instruments are configured to carry out the mathematical function of a normalised input of 0 to 1 unit. So for a 4 to 20mA input combination the input A units will be - Input = (IA - 4) / 16 units. Input B will be computed likewise. The specifications specific to each function are as follows:

Multiply A x B = O/P                 Divide A / B = O/P                Square Root Extraction   Root A = O/P

Multiplication                        [(A x B) x 293.2]
with Temperature                  --------------------   = O/P   where C = O at 20C with a 1V / 10C change

Mass Flow Computation

Squarer A x A = O/P              Rectangular Weir Lineariser  A3/2 = O/P  ### More from Process Instrumentation:
