More companies are requiring calibration and certification of all production equipment. The Watt Meter will provide this certification as well as preventing the loss of product though improper cleaning. Sensor Module with Scope V/A connectors Sensor Module Digital Measurement Console Attaches to Computer Up to 4 individual Ultrasonic or Mega Sonic tanks can be monitored at one time, A software controlled relay will shut down any tank that exceeds its set point. The Ultra / Mega Sonic Watt meter and controller consists of a digital meter, up to 4 individual sensors and computer software that allows the complete monitoring of the generator output.  The generator outputs are connected to a sensor module and then to the generator. The sensor displays the Peak, Average and Reflected power on the LCD meter face. A built in relay can control or send and output signal  to an alarm or to a relay to shut off the Mega Sonic unit or to sound an alarm. The sensor relays the information to the Watt Meter and to an output [BNC] connector for an Oscilloscope. Up to 4 individual generators can be monitored using one Watt Meter. The Information is also displayed on the watt meters own software via a USB connection installed in a laptop or other computer. The generator can be easily calibrated by using the watt meter and its own software alone or in combination with an Oscilloscope.  An output port on the Watt Meter sends a signal to a relay that can be used to either sound an alarm or turn off any generator that exhibits a high or low power output. The Watt Meter software has a number of screens that display the peak and average power output of the generator.  The data can be saved and used with other programs, such as spread sheet or math cad software. Additionally the watt meter displays the reflected power present in the cable. Increasing reflected power indicates a problem with the transducers or the generator. Each sensor has 2 additional BNC connectors for a PC based oscilloscope that will display the wave forms for Volts, Amps and Frequency on its software. This is invaluable for analyzing and tuning the phase of the generator. Several types of PC scopes are available for use with the WM-2008 The TM associates Watt meter offers a NIST calibrated instrument that allows up to 4 different Mega Sonic tanks to be calibrated and monitored at an exceedingly reasonable cost.  When used with our L-2001-4MS probe system the combination of the 2 instruments allows complete monitoring and evaluation both of the generator power and the expressed power in the Mega Sonic bath. The L-2001-4MS displays Power, Spectrum Analysis and process power within the Mega Sonic bath. See our Data Sheet on the L-2001-4 for more information Watt Meter WM-2008 Connection Lay Out for generator monitoring Watt MeterWM-2008-P with Ultrasonic Probe configuration The WM-2008-P Watt meter has one of the 4 sensor ports dedicated and specially adapted to allow the connection of our L-2001 ultrasonic probe. The probe will read the direct watts in the actual cleaning fluid of the ultrasonic or megasonic tank and display that result on a Bargraph and on the Digital Meter. The probe can also be used with the Oscilloscope as a stand alone instrument for displaying wave form, frequency, and spectral analysis of the actual tank power . With the combination of the watt meter and the probe you can compare the power output of the generator with the actual power in the tank. This combination gives you a compete tool for the analysis of any ultrasonic or mega sonic process.

Operating the Oscilloscope Attachment is mere child's play owin Description: Bandwidth 40MHz, 60MHz, 100MHz or 200MHz, Sampling rate 100, 150, 250 or 500MS/s in real time, Equivalent Sampling 50GS/s, Measurement via USB interface, Measurement data can be stored and processed immediately when connected. The oscilloscope screen is similar to the ones of customary oscilloscopes. Operating the Oscilloscope Attachment is mere child's play owing to the unit's auto-set function which enables automatic adaptation of settings to the respective measuring signal, and to its comprehensive range of trigger functions. The true USB2.0 interface allows fast data transfer rate that ensures a quick screen update rate, even when collecting large amounts of data. The plug&play character is very convenient for user to set up and connect the instrument to PC.The device is powered directly from the USB bus that eliminates the transformer.    The  DSO2300 is an intelligent 8-bit two-channel PC-based USB digital storage oscilloscope. It runs on any PC equipped with USB1.1 or USB2.0 using Windows 98/2000/XP. The USB cable provided also supplies power to the unit, so no external power supply is needed. It has up to 100 Ms/s real-time sampling rate and 50MHz bandwidth. The device combines the functions of a frequency spectrum analyzer, waveform recorder, signal generator, cymometer, voltmeter, acoustic analysis graphic instrument, mathematical related graphic instrument voltage meter, and digital storage oscilloscope. All these functions are controlled through a point-and-click PC software interface. It is a small, handheld device that is ideal for engineers, students and anyone looking for an easy-to-use, low-cost and powerful oscilloscope.
