Additel 761A Automated Pressure Calibrator

The Additel 761A Series: Precision Control

The Additel 761A series of automated pressure controllers represents a significant leap forward in calibration technology, offering unparalleled precision and versatility across a broad spectrum of pressure ranges. This series is meticulously engineered to meet the demanding requirements of various industries, from sensitive low-pressure applications to high-pressure industrial processes. At its core, each model in the 761A series integrates advanced control mechanisms with highly accurate sensing technology, ensuring control stability better than 0.005% FS (or 0.003%FS depending on the specific model and range), a crucial factor for reliable and repeatable calibration results. The intelligent design of the 761A allows for both gauge and absolute pressure measurements, with some models featuring a built-in barometer for seamless conversion. This comprehensive approach to pressure control and measurement positions the Additel 761A series as a go-to solution for calibration laboratories, manufacturing facilities, and R&D centers that demand the highest standards of accuracy and efficiency in their pressure calibration workflows.

Tailored Solutions for Every Pressure Need

The Additel 761A series is comprised of several specialized models, each designed to excel in distinct pressure ranges and applications. The ADT761A-LLP is specifically crafted for low pressure calibration, offering a high range module of $\pm 30$ inH2O ($\pm 75$ mbar) and a customizable low range module extending down to $\pm 0.25$ inH2O ($\pm 0.62$ mbar), with an accuracy of 0.05%FS. This makes it ideal for HVAC, medical devices, and environmental monitoring. For broader differential and gauge measurements, the ADT761A-D covers -13.5 to 35 psi (-0.95 to 2.5 bar), coming with a CP35 module and a choice of low range modules down to $\pm 10$ inH2O (25 mbar), offering 0.02%FS accuracy. The ADT761A-500, ADT761A-1K, and ADT761A-1.5K models cater to higher gauge and absolute pressures, generating and controlling from vacuum up to 500 psig (35 bar.g), 1,000 psig (70 bar.g), and 1,500 psig (100 bar.g) respectively, all with impressive accuracies of 0.01%FS or 0.02%FS. Each of these includes high-range CP modules and preconfigurable low-range modules. Finally, the ADT761A-BP is a dedicated barometer calibrator with a range of 100 to 1200 hPa and 0.01%FS accuracy, perfect for meteorological and aviation applications. This diverse range ensures that there’s a 761A model perfectly suited for virtually any pressure calibration challenge.

Unwavering Stability and Rapid Response

Across the entire Additel 761A series, a commitment to exceptional performance is evident in its unwavering stability and rapid response time. Most models in the series boast a control stability of 0.003% FS, a remarkable feat that ensures consistent and repeatable pressure generation. The ADT761A-LLP, designed for ultra-low pressures, maintains control stability better than 0.005%FS or 0.05 Pa, which is critical for highly sensitive measurements. The ADT761A-BP, a barometer calibrator, offers exceptional stability of 0.02 hPa. This superior stability minimizes pressure fluctuations, ensuring that the Device Under Test (DUT) is exposed to a precisely controlled and stable pressure environment. Furthermore, the 761A series offers a typical response time of $\le 40$ seconds, allowing for quick and efficient pressure changes between setpoints. This combination of high stability and swift response significantly reduces calibration cycle times, boosting productivity in busy laboratories and production lines. The 761A’s ability to quickly reach and maintain target pressures with such precision makes it an indispensable tool for critical applications where both speed and accuracy are paramount.

Comprehensive Measurement and Source Capabilities

The Additel 761A series is not merely a pressure controller but a comprehensive calibration solution, featuring extensive measurement and source capabilities that enhance its versatility. Beyond precise pressure control, these units offer robust electrical measurement functions. They can measure mA from -25 to 25 mA with high accuracy ($\pm (0.008\%\text{RD}+1.0\mu \text{A})$) and V measure from -300 to 300 mV ($\pm (0.008\%\text{RD}+6\mu \text{V})$) and auto-ranging V measure up to 30 V. This allows for direct calibration and troubleshooting of pressure transmitters, which typically output current or voltage signals. The inclusion of a 24V loop power source (50 mA max loading) further simplifies transmitter calibration by providing the necessary power without external equipment. The units also offer mA source capabilities (0 to 25 mA) and V source capabilities (0 to 16 V), enabling the simulation of sensor outputs for comprehensive system testing. Additionally, the pressure switch test function is invaluable for verifying the setpoints of mechanical, NPN, and PNP switches, with a fast response time of $<10$ ms. This all-in-one functionality streamlines calibration workflows, reduces the need for multiple instruments, and enhances overall efficiency.

Intelligent Design for User and Device Protection

The Additel 761A series incorporates intelligent design features focused on both user convenience and device protection. The instruments feature a high-resolution display, offering 6 digits, and up to 7 digits with internal 0.01%FS modules, ensuring clear and precise readings. They support an extensive list of 28 selectable pressure units, along with the ability to define custom units, providing flexibility to meet specific industry standards globally. Critical for safeguarding the investment, the 761A includes misuse protection up to 30 V on any two sockets, preventing damage from incorrect electrical connections. The temperature compensation ensures accuracy within a range of 18∘C to 28∘C, with precise temperature coefficients applied outside this range to maintain measurement integrity. Furthermore, the ability to support HART and PROFIBUS PA communication (though details weren’t provided, it’s a common Additel feature) ensures seamless integration with smart instruments and modern industrial control systems. These thoughtful design elements collectively contribute to the Additel 761A’s reliability, ease of use, and long-term performance in diverse and demanding calibration environments.
