16_pH Control using the Tiger 320 Series


The Tiger 320 Series controller using a pH sensor input module operates directly with standard pH sensor outputs. For quick and easy sensor calibration, the Tiger 320 Series controller has On-demand single and two-point calibration functions from the front panel program button.

25_Can Label Glue Application Machine


Our customer manufactures machines for applying labels to cans. They require a controller to control the temperature of the glue and glue roller. The controller also needs to control the length of time the feed mechanism operates to feed the label over the glue roller and spin the can to apply the label. Texmate installed a Tiger 320 Series DI-503 3-display programmable meter controller (PMC). Two thermocouple inputs control the temperature of the glue and the glue roller and inhibit the machine so that it will not operate unless the glue temperature is within set limits. A timer controls the clutch, which controls the label feed and can spin time. The timer is configured for 0.001 seconds resolution and is easily adjustable by the operator.

27_Boiler Energy Calculation Macro


Our customer supplies hot water from a heat exchanger to other users and charges them for kilowatt hours (kW.h) used. The customer supplied calculation to compile the macro was: The difference between water temperature out and water temperature returned x a factor x flow in liters per second. For flow rate in liters/min -> kW - Flowrate (1/m) / 60 x dT (C) x 4.190 -> kW - Flowrate (1/m) x dT (C) x 0.06983333

32_Precision Low Resistance Measurement with Temperature Compensation


For quality control, our customer requires to measure the resistance of hot copper coil windings. Texmate installed a Tiger 320 Series DI-50E meter. A constant current is passed through the coil and the resistance calculated. To compensate for temperature variation the infrared sensor monitors the coil temperature.

39_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.

42_Smoke Density and Temperature Monitor


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.

46_Greenhouse Ventilation Controller


Our customer has a greenhouse. The greenhouse temperature is controlled by opening and closing the roof vents using a forward and reverse motor. When the temperature rises above the setpoint, the vent actuator motor operates for a programmed ON-time opening the vents 10 degrees. After a programmed OFF-time, if the temperature is above the high / high setpoint, the vents open in 20 degree increments until the temperature falls below the high setpoint.

47_Greenhouse Multi Channel Ventilation Controller


Our customer has greenhouses. The greenhouse temperatures are controlled by opening and closing the roof vents using a forward and reverse motor. When the temperature rises above the setpoint, the vent actuator motor operates for a programmed ON-time opening the vents 10 degrees. After a programmed OFF-time, if the temperature is above the high setpoint, the vents open in 20 degree increments until the temperature falls below the high setpoint.

51_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.

55_Wet and Dry Bulb Humidity Measurement and Control


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.

57_Manual / Auto Station


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.

58_Frostmate Frost Risk Management System


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.
