Loop Calibrators

Loop Calibrators

Our loop calibrators deliver the accuracy and functionality you need for maintaining and calibrating 4 to 20mA loops. They allow you to calibrate milliamp instruments by reading, sourcing and simulating. Transcat offers premier products from Fluke, Druck, Altek and PIE within our calibrator category. Recorders, indicators, and additional instruments with 4 to 20 mA loop input can be calibrated with a handheld device from our inventory. You’ll be able to quickly perform checks on wiring or receivers. For testing in explosion-susceptible environments, we offer intrinsically safe loop calibrators. You can also find compact devices with specialized features such as automatic leakage indication, lab-level accuracy, or HART compatibility.

 

Choosing a mA Loop Calibrator

 

Handheld calibrators will vary by operational modes, features and design. They may be built for plant, field or shop applications. Models with an internal loop power supply allow for simultaneously powering and reading a transmitter. When shopping for loop calibration products, you may wish to review the following characteristics:

  • Accuracy
  • Milliamp loop functionality
  • Overload protection
  • Power source
  • Intrinsic safety
  • Speed of checks
  • Display and interface

 

The Most Popular Milliamp Calibrators

 

A Fluke 715 volt/mA calibrator comes in a compact design. It is EMI tolerant, plus resistant to dust and splashes. You can use it to simulate a two-wire transmitter. The Altek 334A model checks, calibrates and measures current-signal instruments in a 4 to 20 milliamp DC loop. It’s an instrument for every point in the loop. The PIE 334 and Fluke 707 build upon the functionality of the Altek 334A, while contributing additional design and technology improvements. The GE Druck UPS-II loop calibrator can power and read two-wire transmitters during field calibrations. It features auto-stepping for accurate, hands-free calibrating.

 

Buy Calibrated Loop Calibrators Only From Transcat

 

Because Transcat operates dozens of ISO 17025 Accredited Calibration Labs across the United States and Canada, we are uniquely positioned to offer new instrument calibration services on most of the items we distribute.  If your quality system requires that your instruments have a valid calibration certificate at all times, take advantage of our calibration services for loop calibrators so that your instrument arrives ready to be put into use.
