Ideal for Industrial Automation and Production
The 845-PE-RS is a Power Meter that allows connectivity of smart power sensors to automation systems and computers using RS-232 communication. When equipment space is tight or the automation system (PLC)/computer is mandating RS232 communication, 845-PE-RS is an ideal solution. In addition to RS232 output, it also has a configurable analog output which can work in two modes raw and digital. It can reach output voltage of 0-10 Vmax. Its robust connector makes it ideal for use in a semi-industrial environment, assuring firm connectivity of the cable.
The 845-PE-RS, can be integrated into 3rd party systems using a dedicated command set or used with Newport PMMmanger. PMManagerTM is a powerful, easy to install, PC application software that controls the power meter and takes measurement data. The 845-PE-RS includes a calibration certificate, power supply, RS232 cable and a PMManager quick installation guide.
Analog Output
The 845-PE-RS features an analog output, allowing easy connectivity to external controllers or test equipment. Its robust connector makes it ideal for use in a semi-industrial environment, assuring firm connectivity of the cable. There are two different optional modes of analog output available - Raw or Digital:
- ‘Digital’ analog output is a calibrated voltage representation of the precisely measured (processed) laser power, where the user selected power range is matched to user selectable full-scale values of either 1, 2, 5 or 10 Volts – useful for reading the measurements into an automation system for control and monitoring.
- ‘Raw’ analog output is a continuous non-digitized amplified signal, sourced directly from the sensor with little conditioning, and routed to the analog output voltage - useful for analyzing the temporal shape of fast laser pulses with photodiode sensors.
Additionally, the 845-PE-RS can function in an autonomous mode, meaning once configured it can measure standalone without any external communication when connected just to a sensor and it’s power supply. In autonomous mode the 845-PE-RS will continue to produce an analog output voltage relative to the measurement – even after a restart.
Low Frequency Power Mode
Low frequency power mode is useful when measuring the average power of pulsed lasers with a frequency in the 5 - 100Hz range. Using the regular power mode with such a laser source can cause beating effects and saturation of the electronics, which causes unstable or incorrect readings in many cases.
An example of such relevant laser sources are VCSEL's, which the 845-PE-RS when in “Low Frequency Power” mode can measure, with steady accurate power readings.
