120K-W
Calorimetric Sensor, BB Type, 10-120 kW, Ø200 mm, 900-1100 nm, Water-Cooled

WaterFlowMeter PC Application

Software: WaterFlowMeter PC Application
Power measurement based on water temperature and flow rate.

Firmware: Firmware of sensor can be upgraded via WaterFlowMeter PC application.
To download the firmware file go to: "Help/New Firmware" screen in WaterFlowMeter PC Application.

Note: When running the WaterFlowMeter PC Application, the Water Flow Meters (6K-W, 120K-W & 150K-W) are connected directly to the PC via supplied RS232 cable. If you want to use the Water Flow Meter with an Ophir power meter or with an Ophir interface with StarLab, the sensor operates as a calorimetric sensor measuring power only.

Choosing a Thermal Sensor

In this short “Basics” video we review the use – and selection - of thermal sensors for measuring low, medium and high laser powers.

Sensors for Measuring Laser Power

In this short "Basics" video we review in general how one goes about measuring laser beam power, so that you'll have a clear understanding of what the different sensor types are, and when to use each type.

Measuring Very High Power Laser Beams

Laser beams with powers of many tens of Kilowatts are becoming more and more common in today's applications, industrial as well as research. This video will discuss the technical challenges in measuring such lasers, and will show you a range of solutions now available from Ophir for measuring up to 100KW -- safely, and accurately.

Water Cooled Sensors: Things to Look Out For

Water cooled sensors are commonly used when measuring laser beams of more than a few hundred watts. In this video, you will learn about some critical issues you need to consider when using water cooling, such as water temperature, water flow rate, and corrosion prevention.

Thermal Sensor Calibration

As the spectral sensitivity of the absorber used for the power and energy measurement is not fully linear, Ophir sensors get a high precision calibration by default with more than one wavelength.

Each thermal sensor is calibrated independently of a particular Ophir power meter with its calibration information contained in the DB15 plug. When the sensor is connected to the meter, the meter reads and interprets this information to display a calibrated reading. Each power meter is calibrated independently and has the same sensitivity as an other meter within about 2 tenths of a percent.

Unless otherwise indicated, Ophir sensors and meters should be recalibrated within 18 months after initial purchase, and then once a year after that.
