About Absolute Process Instruments
Absolute Process Instruments Signal Conditioning
Absolute Process Instruments was founded in 1988 in Mundelein, Illinois, beginning with a line of signal conditioners built for industrial process applications. The company grew its product range steadily by emphasizing quality, fast delivery, and direct responsiveness to customer requirements rather than expanding through broad acquisitions.
In 2000, the company and its Cecomp Electronics division moved into a new 12,000-square-foot headquarters and manufacturing facility in Libertyville, Illinois, to accommodate continued growth. Strategic partnerships followed: a 2002 alliance with GMC Instruments of Germany and a 2005 distribution agreement with A.P.C.S. of Australia extended the reach of its signal conditioning products across North America.
The core business remains designing and manufacturing signal conditioning and signal interface products for the industrial marketplace, serving water and wastewater treatment, chemical manufacturing, and related process industries. ChatMRO helps engineers and procurement teams match signal conditioner specifications against their process instrumentation without digging through technical datasheets, and our team supports RFQ submissions for single units or recurring plant orders.

Frequently asked questions
What is a signal conditioner and when do I need one from Absolute Process Instruments?
A signal conditioner converts, isolates, or scales a raw sensor signal (such as from a thermocouple, RTD, or pressure transmitter) into a standardized output a control system can use. You'll need one whenever your process instrumentation's native signal doesn't match the input range expected by your PLC, DCS, or recording equipment.
Does Absolute Process Instruments supply products for water and wastewater treatment plants?
Yes — water and wastewater treatment is one of the company's core served industries, alongside chemical manufacturing and broader industrial process control. Their signal conditioning products are designed to interface with common process instrumentation found in treatment plant control systems.
What's the relationship between Absolute Process Instruments and Cecomp Electronics?
Cecomp Electronics operates as a division alongside Absolute Process Instruments, and the two moved into a shared Libertyville, Illinois facility in 2000 to support combined manufacturing growth. Both divisions focus on signal conditioning and related instrumentation for industrial customers.
Are Absolute Process Instruments products compatible with international signal standards?
The company's 2002 strategic alliance with GMC Instruments of Germany and 2005 distribution agreement with A.P.C.S. of Australia reflect ongoing work to align with signal conditioning standards used outside North America. Confirm your specific standard or certification requirement with our team before ordering.
How do I find the right signal conditioner without an exact model number?
Describe the input signal type, required output range, and the process application involved, and ChatMRO's AI will match it against the indexed Absolute Process Instruments catalog. This is especially useful when replacing an obsolete conditioner where the original model number is no longer legible or available.
