| SENSOR TECHNOLOGY | |
| TEMPERATURE SENSORS | |
| NTC/THERMISTOR | Non-linear negative temperature coefficient of resistance over the complete temperature range. Used for precise tempearture monitoring, control & switching in motor & transformer windings, bearings, bus bars & industrial machines. |
| PTC/THERMISTOR | Ceramic semi-conductors with very high positive temperature coefficient. Used for the thermal protection of heavey duty motors & transformers, the resistance of the devic rises very steeply with relatively small incraeses in temperature, thus triggering the switching function when the rated operating temperature is reached. |
| PTC/PT 100 | A temerature dependant device, the resistance of the PT100 rises linearly with the temperature. Used for precise temperature monitoring, control and switching in motor & transformer windings, bearings, & industrial machines, where errors in measurement have to be excluded. A variety of housing are available. |
| PTC/Si (KTY) |
Silicone temperature sensors with a nearly linear positive temperature coefficient of resistance over a wide temperature range. Used for precise temperature monitoring, control and switching in motor & transformer windings, bearings, consumer/domestic electronics, automotive, heating & air conditioning where errors in measurement have to be excluded. Can also be used for the sensing & control of liquid & gas levels, thermal conductivity, flow velocity & leak tightness of tanks. A variety of housing are available. |
| THERMAL ELEMENT | A thermocouple element housed in a protective tube for the thermostatic control of temperature or 'thermo-voltage', where an electric circuit has leads from two different metals & thus potentially has two different temperatures. This device is generally integrated into electric devices that provide further functions, e.g. digital thermometers. |
| TEMPERATURE & CURRENT SENSORS | |
| T11 THERMAL CUT-OUT | Bi-metal snap element, normally closed contacts, 2.5 amps @ 250 volts AC |
| T12 THERMAL CUT-IN | Bi-metal snap element, normally open contacts, 6.3 amps @ 250 volts AC |
| T22A THERMAL CUT-OUT | Bi-metal snap element, normally closed contacts, 20 amps @ 250 volts AC |
| T22B THERMAL CUT-IN | Bi-metal snap element, normally open contacts, 3.5 amps @ 250 volts AC |
| HALL EFFECT SENSORS | |
| HALL EFFECT SENSOR | Using a magneto resistive sensor, the Hall Effect Sensor can measure speed, angle & location of moving parts in rotating equipment such as electric motors & generators, as well as wheels & measurement of linear movements. The signal is then sent to the control electronics. |
| INDUCTIVE SENSORS | |
| INDUCTIVE SENSOR | An electromegnetic induction sensor, which measures the speed of rotating equipemnt such as electric motors & generators & deliveres a speed proportional output signal to the control electronics. |
| LIQUID LEVEL SENSORS | |
| LEVEL SENSOR | The electronic level sensor is used where liquid levels must be maintained within specific parameters. If levels move outside of the parameters, an LED lights up to signal this. Minimum and/or maximum levels may be monitored in containers of all types, laboratories, filter systems & water purification plants. |
| FLOW SENSORS | |
| LIQUID FLOW SENSOR | The electronic liquid flow sensor is used where liquid flow levels must be maintained within specific parameters. If levels move outside of the parameters, an LED lights up to signal this. Flow levels may be monitored in containers of all types, laboratories, filter systems & water purification plants. |
| GAS FLOW SENSOR | The electronic air flow sensor is used where air flow levels must be maintained within specific parameters. If levels move outside of the parameters, an LED lights up to signal this. Air-flow levels may be monitored in air ventilation canals of machines & plants, laboratories, filter systems, clean rooms. |
| ELECTRONIC CONTROL & APPLICATIONS TECHNOLOGY | |
| OVER-VOLTAGE PROTECTION | |
| RC MODULE | Reduces over-voltage peaks which result from the switching of magnetic coils in electric motors. |
| VARISTOR | The Varistor is used to pretect the windings of electric motors from damage due to voltage peaks. |
| BRAKE RECTIFIER | |
| BRAKE RECTIFIER | Enables electric motors to be stopped quickly to avoid dangerous situations. Particularly suitable for motors on elevators, elevated platforms, cranes & machine tools. |
| CURRENT RELAY | |
| CURRENT RELAY | Avoids delayed reaction times on the mechanical brakes of electric motors by switching off the DC voltage to the brake coil electronically & contact free, thus reducing braking times. |
| MOTOR START CAPACITOR RELAY | |
| MOTOR START CAPACITOR RELAY | Controls the connection between the motor start capacitor & motor. Particularly suitable for single phase motors or 3 phase motors at single phase demanding freequent switching. |
| TEMPERATURE MONITORING RELAYS | |
| TMS/PTC | Used in conjunction with PTC/Thermistors, the TMS/PTC relay monitors the temperature of windings in electric machines & protects them from thermal overload. When the PTC/Thermistors reach switching temperature, the TMS/PTC relay cuts power to the equipment which it is monitoring, then reactivates automatically when the equiment has cooled. |
| TMS/KTY | Used in conjunction with PTC/Si (KTY) sensors, the TMS/KTY relay monitors the temperature of windings in electric machines & protects them from thermal overload. When the PTC/Si (KTY) sensors reach switching temperature, the TMS/KTY relay cuts power to the equipment which it is monitoring, then reactivates automatically when the equiment has cooled to 5oC approx. below switching temperature. |
| BATTERY POWERED CONTROL UNITS | |
| SPRAY CONTROLLER | Battery powered electronic control of an electric motor that pumps liquid from a storage tank to a hand-held spray gun. Portable battery powered liquid pumps are generally used in gardening, agriculture & remorte locations without power supplies. |
