Pressure-module flexibility
One of the ADT715’s main advantages is its modular architecture. Internal modules cover a wide range, including examples such as:
- CP30M: −15 to +30 psi
- CP100M: −15 to +100 psi
- CP500M: −15 to +500 psi
- CP1KM: −15 to +1,000 psi
- CP3KM: −15 to +3,000 psi
- CP6KM: −15 to +6,000 psi
- CP10KM: −15 to +10,000 psi
- CP15KM: −15 to +15,000 psi / −1 to +1,000 bar
The high-precision gauge modules specify accuracy of 0.01% of reading or 0.005% FS, whichever is greater, with a stated precision of 0.008% reading or 0.004% FS, whichever is greater.
Important capabilities
1. Five-channel pressure monitoring
The ADT715 can simultaneously monitor up to five pressure inputs using internal modules plus two external ADT161 modules. This is particularly useful for comparing multiple pressure devices during calibration.
2. Gauge/absolute pressure measurements
A built-in barometric module can be used to support switching between gauge and absolute pressure measurements. The higher-accuracy BPH barometric option is specified at ±10 Pa.
3. Laboratory and field flexibility
Although primarily a benchtop instrument, the ADT715 has a foldaway handle and optional rechargeable battery, while rack-mount provisions allow integration into calibration systems.
4. Data connectivity
The instrument provides USB, Ethernet and HDMI interfaces, with Wi-Fi available as an option. This makes it suitable for computer-based calibration and data-recording setups.
Typical applications
- Pressure gauge calibration
- Pressure transmitter calibration
- Calibration laboratory reference measurement
- Comparing multiple pressure standards
- Hydraulic and pneumatic pressure testing
- Manufacturing test systems
- Process instrumentation verification
- High-accuracy pressure data logging/monitoring
Additel specifically positions the ADT715 for calibration laboratories, manufacturing environments, and high-accuracy process applications.
Where it fits in Additel’s product range
The ADT715 is primarily a precision pressure measurement/readout instrument, rather than an automatic pressure generator. For example, the Additel 761A is an automated pressure calibrator that generates and controls pressure, whereas the 715 is intended to provide highly accurate pressure measurement and multi-channel monitoring.
Bottom line: the ADT715 is particularly interesting when you need a high-accuracy reference indicator with multiple pressure channels and interchangeable pressure ranges, rather than simply a portable digital pressure gauge.
