Pressure switches and high-level sensors in the field

Excellence for the agricultural sector

Pressure switches and high-level sensors developed using Euroswitch cutting-edge technology and know-how for application in the field of agricultural machinery.

Euroswitch from Sale Marasino, near Brescia, Italy, a worldwide leading designer and manufacturer of sensors of excellence, has developed a range of innovative products for use in numerous fields of industry, including the agricultural sector, where the company has come out with a series of fully customizable solutions to meet specific application requirements and advanced performance, which are ideal for use on agricultural machinery.foto_trattori

Pressure switches with an integrated connector

The design and manufacture of pressure control devices is an important part of the company’s core business, which is supported by a more than three-decades’ extensive know-how in the industry. Euroswitch pressure switches are well-known and appreciated on international markets as being highly performing in terms of efficiency, reliability and safety. The product range has been constantly upgraded to meet all possible production needs in the most varied sectors. Pressure switches are available with adjustable or fixed calibration (-900mb to 40 bar) and NO/NC or SPDT contacts, and the range comprises diaphragm or piston-operated pressure switches, pressure switches with adjustable or steady hysteresis, differential filter clogging indicators and vacuum switches, plus custom versions in which the body, materials, wiring and other features are tailored made.  IP54 and IP67 caps and connectors are available for all models. Custom versions with wiring to drawing and connectors up to IP6K9K index of protection are also available.

Particularly suitable for application in the agricultural sector are the versions with the connector directly integrated with the sensor body, supplied with various types of connection (Deutsch, AMP Superseal, AMP Junior Timer and M12x1), for protection up to IP67/IP6K9K.

This is the case of pressure switches models 40, 41, 41B and 41C;  vacuum switches model 357; filter clogging indicator model 80;  thermostat model 506 and temperature sensors model 580.

Fuel level sensors

Resistive fuel level sensors have been designed specifically for use with non-conductive liquids such as fuels and oils. The operating principle of these sensors is based on the sliding-contact potentiometer, which is anchored inside a foam nylon float and gives a variable resistance value based on the fuel level when the contact slides on an FR4 gold-plated  printed circuit board.

With the correct number (usually 15) and length of sectors on the printed circuit board, it is possible to linearize the measurement to adapt the sensor to any type of tank or instrument, either analogue or digital. A normally-open output contact closes to ground when the fuel reaches the desired reserve level. The presence of a plenum chamber considerably reduces oscillation. An optional check control is available with an additional electronic circuit that checks the reserve light on start-up by switching it on for a few seconds and during normal operation introduces a signal delay to prevent the light flashing during rolling and pitching of the vehicle. The electronic components are located in the flange and resin-sealed for protection. Thus configured, the resistive level indicator can be used in any tank containing a non-conductive liquid (e.g. leaded or unleaded petrol, diesel oil) and mounted either from above or below, at a maximum angle of 25°.

Hall-effect position, speed and rotation sensors, designed to detect the rotation speed and the angular position of fast-rotating parts, such as gears, phonic wheels, camshafts and crankshafts.

Hall-effect position, speed and rotation sensors

These sensors are designed to detect the rotation speed and the angular position of fast-rotating parts, such as gears, phonic wheels, camshafts and crankshafts. Unlike other sensors on the market, they do not require laborious and costly line-up operations during installation as they are equipped with a single sensitive element. The sensor contains the electronic circuit for protection against supply voltage reversals and output short-circuits. The vast range of supply voltage, normally between 6VDC and 24VDC, and a maximum operating frequency of 15KHz, make these sensors ideal for use in heavy-duty applications. These sensors feature a protection class up to IP69K and are designed for use in very demanding work environments (e.g. hot and dusty) and can withstand  cleaning operations on machines that are usually carried out using high-pressure washers.

Euroswitch sensors come with various types of fixing and resistance to environmental conditions. The materials used (brass, aluminium alloys, technopolymers) make them suitable for use in applications requiring lightness, strength and space-saving.

Temperature sensors

Euroswitch offers a wide range of probes and sensors that can be customized on request to meet all possible temperature control or setting requirements in the manufacture of farming and earth-moving equipment.
