Cutting Control_________app_15......AC Current Measurement with Load Control


Our customer has a large log saw with a log feed motor and requires to optimize efficiency of the cutting operation. The log feed motor speed is controlled by the 4-20 mA output scaled from the saw blade motor current. As the saw motor load increases above 90% load, the log feed motor slows. If the load increases above 120%, the feed motor stops. If the load increases to 150%, the saw motor stops.

Motor Control___________app_53......Motor Generator-Set Frequency Control


Our customer has a motor generator set that requires to be controlled at 60 Hz output frequency. Texmate installed a DL-40F controller to measure and display the frequency and to control the motor speed control actuator via the 4-20 mA analog output.

Plating Control__________app_17......DC Amps and Amp / Hr Controller


The customer has an application that requires to: 1. Display Amps from a DC shunt. 2. Display and control from dual totalized amp/hrs. The amp/hrs from totalizer 1 operate Setpoint 1. At programmed amp/hr intervals, a pump starts for a programmed On-time to pump replenishment chemicals to the plating tank. When Setpoint 1 energizes, totalizer 1 resets to 0, the pump cycle starts, and the amp/hrs totalizer 1 restarts.

Power/Energy___________app_31......DC Watt Hours or Kilowatt Hours Measurement and Control with Data Logging


Our client has multiple customers on a DC power supply system and needs to know the watt hours (W.hr) or kilowatt hours (kW.hr) used by each customer. Texmate installed a Tiger 320 Series DI-50E meter to measure the DC volts from the power supply on Channel 1 and the DC amps from a DC shunt on Channel 2. The meter records the result of Channel 1 x Channel 2 as W.hr or kW.hr and continually displays this on the operational display.

Power/Energy___________app_34......Single Phase Measurement and Control


It is no longer necessary to use combinations of transducers to achieve a power measurement and control system. A Texmate Tiger 320 Series DI-503 meter, installed with a single-phase power input module, calculates and displays volts, amps, Hz, watts, watt hours, and power factor from a single-phase 2 or 3-wire voltage and current input.

Power/Energy___________app_44......Peak Demand.


Demand and peak demand are important measurements for large consumers of electricity. This is because the price utilities charge for electricity is related to the peak usage of the consumer over the billing period. The **Electronic Demand Meter** from Texmate is ideal as a submetering system that can measure and track demand and peak demand in different parts of the factory. This information can then be used to manage the overall peak demand strategy of the factory. If the real-time clock option is installed in the **electronic demand meter**, the meter can log or print the time the peak demand occured. The 6 setpoints can be used for load switching or alarms. If an IWO2 watt input module is installed, the amps, volts, frequency kW, and kWh power factor readings can be viewed by using the UP and DOWN buttons.
