Our customer operates a gas dispenser that fills gas cylinders of unknown volume and calculates the cost in dollars.
The meter automates the control process through a macro. In the diagram below, both valves 1 and 2 are CLOSED at the beginning of the process (the default position). When the hose connects to the gas cylinder, the safety switch triggers the macro. Valve 1 OPENS, pressurizing the small reference cylinder of known capacity, and the meter stores the pressure data measured from the pressure transducer.
Our customer carries out stress tests on beams to determine the peak load pressure and the linear displacement reading at the point of failure.
Texmate installed a Tiger 320 Series DI-50E meter configured to display and hold the peak readings, load pressure on Channel 1, and linear displacement on Channel 2.
Our customer operates a trucking company and requires a printed record of the weight of the load being carried.
Texmate installed a Tiger 320 series DI-50E meter with a permanently connected serial printer and two remote pushbutton switches. The meter is connected to the weighbridge, calibrated to read in the appropriate engineering units, and programmed for the remote tare functions with all non-application codes blanked out.
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.
Outdoor growers in intermittent or low rainfall areas require irrigation controllers. The controller input is usually from a tipping bucket rain gauge or a flow sensor.
Control requirements: If more than X amount of rain falls within a programmed time, the irrigation cycle is interrupted. If Y amount more rain falls within the programmed Off-time, the irrigation cycle is interrupted for a longer time.
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.
With the mounting pressure to clean up the atmosphere, many local authorities are now legislating the maximum density of smoke released into the atmosphere from chimneys. They now require chimney output opacity (smoke density) and temperature to be monitored, averaged and recorded at one minute intervals with a date and time stamp.
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.
Our customer requires the amount of resin and roving used during their manufacturing operation to be calculated, monitored, and recorded on a job-by-job basis, providing them with accurate costing and stock information.
Texmate installed a Tiger 320 Series controller and connected it to the resin feedline flow transducer and the roving weighing platform pressure transducer.
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.
Wet and dry bulb humidity measurement, using two temperature sensor probes, is perhaps the most reliable method of accurately calculating humidity for low temperature applications in industry today. Both sensors are mounted close together, with one designated the dry bulb sensor and the other the wet bulb sensor. The wet bulb is kept wet using a moistened cotton wick.
The wet bulb is cooled relative to the dry bulb by heat loss due to moisture evaporation from the wet bulb wick. The rate of evaporation is dependent on the ambient temperature and humidity.
In many industrial applications it is necessary to be able to control a device manually. Often a potentiometer or rotary switch is used, but this method can be too coarse and not easily repeatable. Texmate have developed a versatile and easy-to-use selection of manual stations, using their Tiger 320 Series controller, that produce an accurate, digitally controlled and scaled 4 to 20 mA or 0 to 10 V output.
Frostmate is an integrated frost risk management system that reduces the risk of frost damage to an orchardist's crop. A sophisticated control and monitoring system constantly monitors the orchard environment combining both temperature and humidity to deliver a reliable prediction of frost conditions. When frost damage is imminent, the Frostmate automatically initiates the timely delivery of water spray to the area at risk, raising the humidity level. Water delivery is maintained in a continuous cycle to the affected zones until the frost conditions have abated, ensuring better crop protection and conserving resources such as water and power.
