An instrument is only as smart as the commands that drive it.
Traditionally, to receive a pressure indication from a digital pressure transducer, a user must query and wait for a response from the device. For Mensor transducers, the operating instructions include a command set that not only query the pressure reading, but also access other information and change settings within the transducer.
"PRESS?" command - Terminal Program
In some applications, continuous output from a transducer is preferred. For processes that require frequent readings, or continuous readings, individual queries are not practical. In some automated processes, readout or data acquisition systems may not be programmed to send command queries for pressure monitoring. In these cases, the transducer can be configured to send constant pressure readings. These outputs aren’t limited to pressure but can also send other information such as the sensor’s temperature and the uncertainty of the pressure indication.
"OUTPUT_MODE" command - Continuous Output - Terminal Program
These commands benefit users that want to easily integrate pressure transducers into their larger system, monitor measurements around the clock or customize their readings to include output frequency, temperature data or the uncertainty at each pressure point.
- Instrument Integration
Setting up continuous readings can help integrate a pressure transducer into an existing control system.
A constant data stream can help an automated system run efficiently and safely without the need for human supervision. Since the instrument is constantly feeding information into a system, if readings are outside of a certain range it can trigger other functions, safety shutoffs, valve releases and bypasses, in order for a system to continue running at optimal levels.
- Constant Monitoring
Also included in a Mensor transducer are commands that enable the transducer to output readings at a certain time increment. Readings can even be taken continuously up to 100 hz. This is useful in order to monitor spikes or anomalies in data. A continuous stream of data can help users troubleshoot fluctuations in readings, monitor a delicate system and alert to any safety issues.
- Customizable Readings
Transducers such as the CPT6020 contain many features that can be configured and reconfigured at any time. Readings besides pressure can be detected and recorded. The data stream is customizable so it can be as simple or as complicated as needed.
Using commands to control and customize data, a single transducer can monitor changes in data such as reading uncertainty and sensor temperature.
"OUTPUT_MASK" command - Terminal Program
OUTPUT_MASK commands are especially useful for customizing data and automating readings. Instead of individually querying a device for separate pieces of information, an output mask can retrieve a set of data points the user has configured such as the combination of pressure, sensor temperature and measurement uncertainty. All the possible output commands are listed in a transducer’s operating instructions.
The transducer’s command set, listed in an instrument’s operating instructions, can help utilize automated features built into the instrument. These commands help large systems run safely and more efficiently. They deliver customizable data sets at a user-selected time and frequency.
