The Setra MicroCal automated pressure calibrator is used as a stand-alone calibration standard for differential and gauge pressure sensors found in critical environments. Setra partnered with NASA to develop the industry's quickest and most stable pressure control for low range applications. The MicroCal combines precise pressure control with high accuracy modular pressure reference providing the quickest and most accurate calibration solution on the market today. The MicroCal is an easy-to-use solution that significantly improves labor productivity and efficiency when compared to the leading competitors, providing immediate ROI.

The Setra MicroCal utilizes modular pressure reference, enabling the user to select the most accurate reference for calibrating the unit under test. Competitive calibrators often use fixed higher range reference sensors that do not allow for proper calibration ratios at the low end of the pressure range. The modular rechargeable battery offers further flexibility to extent available calibration time beyond the standard 8 hours.

The MicroCal is designed to perform calibration checks on installed sensors, pressure switches and gauges that monitor critical applications. The on-board pressure generation system allows for stable & accurate pressure to be applied to the unit under test during calibration, while providing isolation from process background disturbances. The NASA patented technology achieves 0.0002" W.C/step resolution; when combined with the high accuracy the MCPM pressure module, the MicroCal is the ultimate low-pressure calibration device.

When the fast and stable pressure control is combined with high accuracy reference modules and easy to use interface, the Setra MicroCal can reduce overall calibration time up to 80%. This time savings provides almost immediate ROI based on the number of calibrations performed annually.

The easy-to-use 7" touchscreen interface, combined with an intuitive menu structure, provides the user with all the features needed for verification and calibration of differential pressure instrumentation. The MicroCal offers the Expert System feature, which detects and automatically calibrates Setra's Model 269 digital pressure transducer.

Application Notes

Here's how some of our customers used this product.

Calibrating DP Transmitters for Cleanrooms

The Background: Our customer is a pharmaceutical company performing clinical-phase trials of vaccines. The trials are performed in a cleanroom with differential pressure transmitters monitoring the airlocks.

The Problem: The differential pressure transmitters require frequent calibration due to government/pharmaceutical manufacturing protocol. Having a third party perform the calibrations is a costly and time-consuming process. The customer seeks a ways to perform these calibrations themselves.

The Solution: We recommended the Setra MicroCal, an industry standard, which gives the customer the flexibility of performing these calibrations without the need for a third-party allowing them to save money and time. The removable modules also offer added flexibility so the customer is prepared for any low pressure calibration requirement that may arise.
