Beam Stress Test
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.

Flow Rate and Total Flow Measurement.
Paddlewheel and turbine flow sensors are similar in operation as they rely on the energy in the flow stream to spin the rotor. The spinning rotor generates either a sinusoidal or square wave output.

Frost Protection Controller
The Frost Protection Controller is an integrated, low cost frost risk management system that reduces the risk of frost damage to an orchardist's crop. The system constantly monitors the orchard temperature using a Pt100 RTD sensor. When frost damage is imminent, the controller 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.

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.

Gasfüllstation
Unser Kunde hat eine Gasfüllstation, die das Befüllen von Gasbehältern mit unbekanntem Volumen erlaubt und die entsprechenden Kosten berechnet.
Das Messgerät automatisiert den Steuervorgang über ein Makro. Im Diagramm sind die beiden Ventile (Valve 1 und 2) GESCHLOSSEN (Ausgangsstellung). Wird der Schlauch an den Gasbehälter angeschlossen, wird das Makro über den Sicherheitsschalter (safety switch) ausgelöst. Ventil 1 wird GEÖFFNET, ein Referenzzylinder mit bekanntem Volumen wird gefüllt und das Messgerät speichert den anliegenden Druck, der vom Druckumwandler übermittelt wird.

Bewässerungssteuerung
Ein Winzer will sein Bewässerungssystem der aktuellen Wetterlage anpassen, um einerseits den Ertrag zu maximieren und andererseits die Kosten für die Bewässerung zu reduzieren. Dazu ist eine Wetterstation auf dem Weinberg, die Sonneneinstrahlung, Windgeschwindigkeit, Niederschlag und Lufttemperatur erfasst, mit einem Steuermessgerät der Tiger 320 Serie verbunden. Ein Makro, das auf dem Messgerät installiert ist, berechnet aus diesen Daten die Evapotranspiration.

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.

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.

Payload from a Weighbridge
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.

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.

Resin to Roving Ratio and Progress Monitoring System for the Composite/Fibreglass Industry.
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.

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.

Intelligente Niederschlagsmessung für Bewässerungssysteme
Für den Freilandanbau in Gebieten mit geringem oder unregelmäßigem Niederschlag werden Systeme zur künstlichen Bewässerung benötigt. Die Niederschlagsmenge wird dabei meist mittels einer Kippwaage oder eines Durchflusssensors erfasst.
Steueraufgabe: Wenn der Niederschlag innerhalb einer bestimmten Zeit höher als X ist , dann unterbreche den Bewässerungszyklus. Wenn der Niederschlag höher als Y ist, dann unterbreche den Bewässerungszyklus für eine längere Zeit.

Monitor für Rauchdichte und Temperatur
Aufgrund steigender Ansprüche an die Sauberkeit der Luft werden vielerorts Grenzwerte für die Rauchabgabe von Schornsteinen an die Umgebung erlassen. So müssen zum Beispiel die Dichte des Rauchs und die Temperatur der Abluft überwacht, gemittelt und jede Minute mit Datum und Uhrzeit gespeichert werden.

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.
