Logic Beach data loggers are capable of measuring and recording signals from a variety of sensors. Sensors can be utilized in any combination to measure the desired parameters unique to your application. Voltage, current and power measurements are all possible with the proper sensor selection. The parameters you wish to monitor in addition to the AC parameters will direct you to the right data logger for your application. This selection guide is intended to assist with this task.

AC Current is measured using current transformers (CTs). The CTs are placed around a single current carrying conductor and a DC voltage or 4-20mA signal is generated proportional to the amount of current flow. AC current sensors can be loop powered or self-powered and can be split-core (to install CT can clamp around wire) or solid-core (to install wire must pass through CT). The output of the CT is connected to a data logger analog input where it is sampled and scaled from the signal units to engineering units.
Utilizing the unused I/O or by expanding the data loggers I/O with optional interface modules additional sensors may be added to monitor and record other physical parameters such as, temperature, pressure, flow, RPMs, displacement, humidity, etc as well as more AC currents. The following diagram illustrates the Logic Beach products capable of measuring and recording the analog output from AC current transformers.
Kilowatts are a calculated value based upon the measured values of AC voltage and current. Depending upon the number of phases, one to three AC current sensors are placed around the current carrying conductor(s) and a sensing lead(s) is attached to the voltage source. These sensors are typically self-powered via the AC source to which they are connected. Most of these sensors are also split-core (to install CT can clamp around wire) with a 4-20mA signal output signal. The analog output of the kW sensor is fed to a data logger analog input where it is sampled and scaled from the signal units to engineering units.

Kilowatt hours are a function of Kilowatts integrated over time. Kilowatts are a calculated value based upon the measured values of AC voltage and current. One to three AC current sensors are placed around the current carrying conductors and voltage sensing leads are attached to the voltage source. These sensors are typically self-powered via the AC source to which they are connected. Most of these sensors are also split-core (to install CT can clamp around wire). Internal electronics accumulate the Kilowatts over time and then outputs a pulse which corresponds to a predetermined number of Kilowatt hours. The number of Kilowatt hours per pulse is found in the specifications for each Kilowatt sensor.
The pulse output of the kWh sensor is fed to our data logger Digital Counter Input where it is counted for a length of time and then scaled from a “pulse count” to Kilowatt Hours units. HyperWare can then be programmed to accumulate kWh total consumption on a hourly, daily, weekly and monthly basis.
Utilizing the unused I/O or by expanding the data loggers I/O with optional interface modules additional sensors may be added to monitor and record other physical parameters such as, temperature, pressure, flow, RPMs, displacement, humidity, etc as well as more AC currents. The following diagram illustrates the Logic Beach products capable of measuring and recording the digital output from AC Kilowatt hour current transformers.
A thorough power analysis is possible with the HyperLogger PowerPlus™ data logging and alarming system, models HLP-10 and HLP-200. These two products utilize a Power Sensing Harness consisting of one to three AC current sensors placed around the current carrying conductor(s) and three voltage sensing leads attached to the voltage source. The Power Sensing Harness is self-powered via the AC source to which it is connected. The CTs of the Power Sensing Harness are split-core (to install CT can clamp around wire) for easy installation. An electronic circuit internal to the Power Sensing Harness calculates 26 different power parameters and output this data via a serial data stream.
The serial data stream output of the Power Sensing Harness is connected to the data logger HLIM-9 Programmable Interface Module inputs where it is sampled and interpreted to a value for each selected electrical parameter.
The HLP-10 and HLP-200 are also able to monitor physical parameters such as, temperature, pressure, flow, RPMs, displacement, humidity, etc, with the addition of optional Interface Modules installed in the data logger. The following diagram illustrates the Logic Beach products capable of measuring and recording the analog output from AC Kilowatt transformers.
