AUTOMATING YOUR TRIGGER - ON/OFF

Newsletter No.6, January 12, 2017

 

Dataloggers for electrical and industrial purposes revolve around three major objectives: recording, monitoring, and testing.

To automate the recording process, the triggering feature is used in setting up conditions. Graphtec’s robust, independent start and stop triggering capability allows users to capture only the data of interest via event-based triggers or time-based triggers.

In this newsletter, we focus on the triggering feature for all Graphtec portable dataloggers-including the external triggering mechanism in automated testing, monitoring and recording processes.


In various datalogging testing scenarios, the ability to process the data files by utilizing the trigger will simplify the testing process. It eliminates down-time and automates the starts and stops for the datalogging application. For example, recording temperature data for heat treatment in an oven chamber can be initiated when a specified temperature is met per user’s specification. Graphtec dataloggers provide several options for this triggering mechanism. They include threshold level, alarm, external input, date, weekly, and time stamp triggering variables.

All triggering features are available on the GL APS software for Graphtec portable dataloggers. In addition, the scheduling feature will appropriate customized test workload to individual test files in advance. Users will be able to set test plans beforehand and customize tests based on each user’s requirements.

Additionally, the trigger can utilize start and stop sources based on the alarm threshold. Conditions can be applied to each of the input channels to set hourly or daily recordings to best suit the file management structure—suited for each user. Repeat function on the triggering setting will then convert the “Time” (or timer) feature into consistent repeatable test files. At the same time, the file is populated on the internal RAM drive or the external SD card. Wireless recording is also available on the GL100, GL240, and GL840s.

 

EXTERNAL TRIGGERING


In some cases, Graphtec’s recording start and stop sources can be switched on and off using an external triggering feature using a power source from the switch button or power supply of your test fixture. For example: testing battery durability of the loads and temperature levels of the cells can be set to start and stop using the power switches of the battery. This step eliminates the need to switch on a datalogger to start recording—thus providing test engineers an automated datalogging options, eliminating this common human-error associated with test and measurement. 

To utilize this feature, you will need the addition of the B-513 Logic/Pulse cable. Within one of the bare terminal leads, the external triggering cable with the ground connected to the ground wire at 0 to +24V single-ended input will directly feed signal to the datalogger for the external triggering feature. Graphte’sc B-513 cable is available through our authorized instruments distributor

    MONITORING SENSORS WITH ENGINEERING SCALING

    Discovery Newsletter No.4 | July 26, 2016

     

    Graphtec dataloggers have long been regarded as the go-to multichannel, portable datalogger for 10 channel and above applications for recording temperature and voltages signals. In this issue of our discovery newsletters, we explore the engineering scaling feature more in depth as we cover the details on how signals from pressure transducers, flow meters, LVDT displacement sensors and various other signals are used in conjunction with the Graphtec GL series.

    Also, discover how additional testing can be made with various physical parameters like distance, pressure, flow, and speed.

    SPEED, FLOW LEVELS, AND TOTALIZATION

    Tachometer and flow sensors that provide pulse signals for rate and speed of flow can be measured and scaled using the GL series line-up with B-513 logic/pulse cable. Four channels are available for pulse signals in this configuration. “Engineering Unit Setting” is also available for all four channels. When monitoring speed rates from a tachometer or an IR speed sensor, pulse signals can be scaled from the measurement value of sensors available in each rotation to an RPM as shown below.

    For flow signals, the individual pulse signal can be converted to the equivalent flow rate as shown above.

    Totalization of flow rates are provided in total gallon in terms of volume. This can be calculated using the “Instantaneous Count” feature where every pulse signal per sampling rate is chosen (ie. 10 pulse signal per 1 minute interval) and will give you the total volume received under the particular sampling interval (in this case a one minute interval).

    Please consult the Graphtec Technical Sales and Support teams at inst.support@graphtecamerica.com & at inst.sales@graphtecamerica.com to discuss your specific applications.

    GL840-M/WV MULTI-CHANNEL DATA LOGGERS

    Discovery Newsletter No.2 | April 26, 2016

     

    This month, we cover the basic features of the GL840-M multi-input and the GL840-WV withstand-voltage model dataloggers. With these two new models, focus is on the general 20-channel temperature/voltage input datalogger and the voltage-withstand datalogger with higher accuracy, higher voltage input capability and glitch protection. GL840-M is ideal for multichannel measurements of linear voltage output (or 4-20mA current loops), thermocouples, and RTDs. GL840-WV will support requirements for high precision measurement of temperature and voltage as well as high voltage—such as battery cell voltage monitoring and measurement.

    Expandability up to 200 channels

    The key capability of the GL840 is on its expandability of up to 200-channel input measurements using its expansion terminal blocks. The basic configuration for the expansion kit will require an extension cable, extension terminal base, and the 20-channel extension terminal block. The GL840 series, on both the multi-input model and the withstand model, now provides the ability to connect each terminal base in combination with the terminal block—with the extension cable in addition to the traditional method of daisy chaining terminal blocks to each other.
