Switch Mode Power Supply
Switch mode power supplies(SMPS) are an extraordinary array of high frequency alternative. These are the Switching Regulators offers higher efficiency then
liner regulators. In addition the Power Supply SMPS can step-up, down and invert the input voltage. Working principal of Switch Mode Power Supply
A switching regulator is a circuit that uses an inductor, a tranformer, and a capacitor as energy-storage element to tranfer energy sed in medium and high power applications.
Works on 10-40 V DC and directly drive DC relay or PLC gate. Most widely used industrial sensor for sensing position and speed.
The efficiency and life expectancy of a cartridge heater depends mainly on the fit tolerance. Cartridge heaters are typically manufactured .003" to .005"
smaller than the nominal diameter. Drilled holes are typically .001 to .003 larger than the nominal diameter. Inserting a cartridge heater with a nominal
minus of .005" into a drilled hole with a nominal plus of .003" results in a fit tolerance of .008". Although a tighter fit is desirable to efficiently transfer
heat and to get long heater life, a looser fit will help in installing and removing long heaters.
In industrial processes, temperature is often the most important variable to control. Temperature variations cause changes in flow, viscosity, pressure or
Thermocouples are dissimilar wires so joined as to produce a thermally generated mini-voltage when its joint ends are exposed to temperature. Several combinations of dissimilar combinations have become standards and are letter coded. Thermocouples have normally standard lead wires of 12 inches but can also be ordered with longer lead wires. Thermocouples are perishable items and the controller where they connect to may be many feet away. To safe on maintenance costs, use jacks and panels to connect the lead wires from the thermocouples to the extension thermocouple wire (which connect into the control panel). A correct chosen thermocouple extension wire and connetions allows the extension of up to 100ft without affecting the thermoelectric characteristics. If a thermocouple needs to be replaced, it makes sense to replace just the thermocouple with the standard lead wire
Digital Process Controller
The Digital Process controller accept input RTD,Thermocouple Voltage , Current. The controller suitable for Temperature, Pressure Humidity, Level, Flow , Tachometer, Voltmeter, Ammeter . The inputIs passed through suitable filters to eliminate unwanted signals. LowThermal drift operational amplifier ensures good stability. Control setPoint can be set very accurately.TTC-PC are available in many models. LED display provide visual status of the relay.The instrument is housed In a compact sheet metal case . AC Mains or DC Voltage Operated Cold junction compensation is standard feature in Thermocouple input.
