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.

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.

Irrigation Scheduling Controller


Our customer requires water balance studies of water resource allocation for crop management to maximize crop yeild and reduce irrigation costs. A weather station with a Tiger 320 Series controller is set up in a vineyard to measure solar radiation, wind speed, rainfall, and air temperature. A macro installed in the meter and generated by the Texmate Development Software program calculates daily evapotranspiration.

Oxygen Measurement Using a Zirconia Sensor


O2 is an important parameter to measure and control in kilns and furnaces. The diagram below shows the Tiger 320 Series DI-50 controller connected to a Zirconia O2 sensor with a built-in thermocouple. The controller calculates the O2 level from the temperature and mV level of the sensor. The result is then displayed on the controller.

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.
