Tempatron - Temperature and humidity sensors, liquid level sensors, pressure sensors and proximity switches


	*INPUT SENSOR*S

	*PRESSURE SENSORS*
		The SPK range of pressure transducers convert line pressure into a 4 to 20mA analogue signal that can be used as an input to a controller or data acquisition system. Three models are available with operating ranges of -0.5 to 7 bar, 0 to 25 bar and 0 to 30 bar. With an 8-30Vdc power supply and industry standard 7/16 - 20UNF mounting thread, these sensors are suitable for a wide range of industrial applications, particularly in refrigeration and air-conditioning systems. _________________________________________________________________________

	*TEMPERATURE & HUMIDITY SENSORS*
		This range of temperature and humidity sensors is available in wall, surfrace and duct mounting styles. They cover the a temperature range of -10 to 70ºC and a humidity range of 0 to 100%rH. The units are powered by either 9-30Vdc or 12-24Vac and have a selectable 0 to 1V or 4 to 20mA output. _________________________________________________________________________

	*SELEX LEVEL SENSORS*
		The Selex range of PCB mounted sensors provide a low cost solution to the sensing of conductive liquids. They use advanced solid state ferro-magnetic technology to sense the presence of a liquid by detecting the free ions within it. This novel, low impedance technique passes no measurable current through the liquid and provides full galvanic isolation between the supply and the inputs and the outputs. The sensor requires two mutually isolated metallic probes, one of which can be the liquid container itself. _________________________________________________________________________

	*INDUCTIVE PROXIMITY SENSORS*
		These sensors create an inductive field in front of their active surface. When a metallic object enters this area the change in the field causes the output to switch. Available in a wide range of cylindrical, rectangular and ring types, these sensors are suitable for use in many applications, and are particularly suited to harsh environments. The Namur types meet the requirements of DIN standard 19234 and are suitable for use, in conjunction with intrinsically safe amplifiers, in environments where there is risk of explosion. Versions with extended sensing distances, circular H type and spade K type connectors are also available. _________________________________________________________________________

	*CAPACITIVE PROXIMITY SENSORS*
		These sensors contain an oscillator which is influenced by the change in capacitance when a solid or liquid comes into contact with the sensing head. The level at which the sensor output switches can be set with the sensitivity adjustment making them suitable for a variety of materials such as water, wood, metal, powders etc. They are available in 3 sizes - M18, M30 and M40 with DC, AC/DC and relay output versions. _________________________________________________________________________

	*PHOTO-ELECTRIC PROXIMITY SENSORS*
		These photo-electric sensors, or photocells, are made up of a light emitter and a detector or receiver. The variation in luminous signal when the beam between the emitter and detector is interrupted controls the state of the output. The range covers reflection and through beam types in 3 standard packages with axial or 90º beam NPN, PNP, NO & NC outputs. _________________________________________________________________________
