Smart sensors go a little further than the yellow mailbox \nalert flag that tells us whether the postman has come by. Predicting a \ntsunami, measuring radiation levels, or signalling a faulty underground \npiping requires innovation and high quality sensors.<\/p>\n\n\n\n<p style=\"font-size:15px\">Sensors are designed to work electronically or mechanically. Analyzing  measurements provides a wealth of information, for this we refer to <a href=\"https:\/\/www.mobeye.com\/en\/thema\/data-analysis\">our  article<\/a> on data analysis.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-1 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<p> <strong>Standard industrial sensors<\/strong> <\/p>\n\n\n\n<p style=\"font-size:15px\">Although sensors come in many shapes and sizes, there are similarities.  Most sensors have a similar output signal, or a standardized method for  reading the measured values. We call these the <em>standard industrial sensors<\/em>. <\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<p> <strong>Generic sensor reader<\/strong> <\/p>\n\n\n\n<p style=\"font-size:15px\">Standardized output signals make sensors widely applicable and usable  for \u201csystem integrators\u201d. It also means that a \u201creader\u201d can be somewhat  generic, capable of reading many types of sensors. And that is exactly  the subject that Mobeye has specialized in.  <\/p>\n<\/div>\n<\/div>\n\n\n\n<hr class=\"wp-block-separator has-css-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">The most common output signals<\/h3>\n\n\n\n<h4 class=\"wp-block-heading\">Potential-free sensors<\/h4>\n\n\n\n<p style=\"font-size:15px\">A potential-free sensor can best be described \nas a contact that can switch \u201copen\u201d or \u201cclosed\u201d. This group includes \nswitches, magnetic contacts and relay contacts.<br><br>An example of a \npotential-free sensor is a magnetic contact, with the fixed part \nattached to the door frame and the magnetic part to a door. When the \ndoor is closed, the two parts are close together and the contact is \nclosed. When the door opens, the two parts separate and the loop is \nopened. The fixed part (on the door frame) has a metal part internally, \nwhich is bent by the magnet and thus acts as a switch.<br><br>A relay is\n a special type of switch that switches when it is powered. The magnetic\n field flips the switch. Where the input voltage can differ per relay, \nthe output signal is always potential-free.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Analog sensors<\/h4>\n\n\n\n<p style=\"font-size:15px\">This group includes sensors with a \u201cvoltage\u201d \noutput. Sensors usually have a range between 0V and 1V, 0V and 5V, 0 and\n 10V, or 4-20mA.<\/p>\n\n\n\n<p style=\"font-size:15px\">As an example we take a specific pressure \nsensor. According to the datasheet, it provides an output voltage \nbetween 0.5VDC to 4.5VDC. It can display a pressure between 0 Bar to 1 \nBar. A measured value of 0.5V corresponds to 0 Bar, an output signal of \n4.5V means a pressure of 1 Bar. There is a straight line between these \npoints, each measured baseline value stands for its own pressure value. \nThe measuring instrument thus displays the pressure by measuring the \nvoltage and recalculating it. By interpreting the values and, for \nexample, comparing them to an alarm limit, the measuring instrument \nbecomes a pressure gauge. The sensor could also have measured a \ndifferent value, for example ammonia, and could have taken the \nmeasurements with the same logic.<\/p>\n\n\n\n<p style=\"font-size:15px\">Analog sensors require power. Depending on the\n situation and type of sensor, this needs to be continuous or only \nperiodic. Mobeye has focused on powering and reading sensors, even with \nextremely low energy consumption. This makes the entire measuring setup \nsuitable for battery-powered operation or powered by solar panels.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Resistance measurement<\/h4>\n\n\n\n<p style=\"font-size:15px\">Many temperature sensors work by changing the \nelectrical resistance of a metal or semiconductor through temperature. \nThe measured temperature is derived from the change in resistance. \nExamples are PT100 and PT1000 sensors.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Pulse generator<\/h4>\n\n\n\n<p style=\"font-size:15px\">A pulse generator is readable via a pulse \ncounter. For example, flow meters usually consist of a (water) wheel. As\n water flows through a tube, the wheel will turn and periodically give a\n pulse which means it closes a magnetic contact. If the water flows \nfaster, the wheel will spin faster. Each turn then stands for, for \nexample, 10 liters of water.<\/p>\n\n\n\n<p style=\"font-size:15px\"><strong>What can Mobeye do for you?<\/strong> <br>Mobeye  is a manufacturer of measurement, log, control and reporting  technology. Several Mobeye products are delivered including a sensor.  Most Mobeye products can read potential-free sensors. For reading out  analog sensors and pulse generators, Mobeye offers the \u201canalog  products\u201d, such as the Mobeye SISTM and Mobeye CML4055. These read out  analog sensors, convert the values to a meaningful unit, and log them in  a graph or tabular form, in addition to monitoring alarm limits. Unique  is that Mobeye products and the sensors also work battery powered, for  situations where no external voltage is available<\/p>\n\n\n\n<div class=\"wp-block-rtgb-call-2-action mkb-call2action\"><div class=\"mkb-call2action__inner container\"><div class=\"cta-content\"><p>Do you want to read a remote sensor, receive notifications or get insight into the values?<br\/>Consult Mobeye for more information.<\/p><\/div><div><a href=\"https:\/\/www.mobeye.com\/en\/contact-form\" class=\"mkb-button mkb-button--accent mkb-button--rounded text-uppercase\">CONTACT MOBEYE<\/a><\/div><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"<p>Sensor measurement Sensors are the artificial senses that help us perceive.
