1. The company
APCS was founded back in 1982 for the design and manufacture of Signal Conditioning modules - after 26 years of operation, APCS was purchased by NESS Corporation, a company with over 120 employees.
NESS's main business is the manufacture and sales of Security and building automation products.

2. What is Signal Conditioning?
"Anything in / anything out" - conversion, isolation, amplification, splitting, monitoring and many more functions for electrical signals or signals from sensors producing electrical signals used in measurement and control applications.
- Isolation
requires non electrical coupling of signals ( magnetic , optical ) - Conversion
changing signals to different levels/type - Amplification
increase of signal level - Monitoring
contact output to alarm process conditions
APCS Signal Conditioners can interface to most types of input signals, and convert these to a dc current or voltage for monitoring or control:
- dc current or voltage
- ac current, voltage, watts, vars, power factor, mains frequency, tap position
- resistance or potentiometer
- temperature using RTD or thermocouple or thermistor
- Load Cell
- Vibration
- Frequency from a variety of proximity sensors
- LVDT (Linear Variable Differential Transformer) used for measuring linear displacement
- Conductivity
- pH, ORP, Dissolved Oxygen
Example: Temperature measurement using Thermocouple
Functions required - Amplification, Linearisation, Isolation and cold junction compensation
APCS also manufacture Calibrators to assist field technicians during testing and installation
