Comprehensive Instrumentation Solutions

Our instrumentation and calibration services cover every stage of an instrument’s lifecycle—from setup and testing to long-term maintenance. We install and configure transmitters, analyzers, and control devices to ensure accurate signal transmission and stable process control. During calibration, our technicians use certified reference instruments to verify readings, ensuring compliance with operational and industry standards.

Current Southwest works closely with maintenance teams to identify performance issues early. Through routine calibration, loop checks, and scaling verification, we detect irregularities in transmitter output, control logic, or wiring that could compromise system reliability. Our work helps clients avoid costly process errors, maintain product quality, and improve overall plant efficiency.

Expert Calibration, Reliable Data

Our technicians are trained and certified through recognized programs including ISA, NCCER, and UL 508A, ensuring that every calibration meets both technical and regulatory expectations. We understand that even minor inaccuracies can lead to significant process disruptions, so our focus remains on consistency, documentation, and technical precision.

Frequently Asked Questions

What types of instruments does Current Southwest calibrate?

We calibrate a wide range of industrial process instruments, including transmitters for pressure, temperature, level, and flow, as well as analytical devices such as pH and conductivity sensors. Our technicians are experienced with both analog and smart (HART/Fieldbus) devices used in municipal and industrial applications.

How often should instruments be calibrated?

The ideal calibration interval depends on the process environment and the instrument type. For critical process control instruments, annual calibration is generally recommended. However, in harsh or high-demand environments, more frequent verification may be required to maintain accuracy and compliance.

Do you provide documentation for each calibration?

Yes. Every calibration includes a detailed calibration report documenting as-found and as-left data, test conditions, and instrument identification. These reports support compliance, audit readiness, and maintenance planning.

Can you troubleshoot existing instrumentation problems?

Absolutely. We specialize in instrumentation troubleshooting, including signal loss, scaling errors, and inconsistent readings. We perform loop checks to trace signal paths between instruments, PLCs, and HMIs to pinpoint and correct performance issues.
