Questions related to electronic circuit design in industrial environments where environmental conditions such as temperature, humidity, vibration, noise are significant and require careful consideration above what would be needed in commercial settings. Includes questions on Industrial Grade parts.

Typically near equal to Grade parts, better than Consumer or Commercial Grade parts, but not as high quality as Military or Aerospace Grade parts, though this varies based on manufacturer. Military Grade parts are often mandated by law or government regulation/standards.

Why is the temperature range of industrial and military products so high?

From Wikipedia the common temperature range for electrical components is: Commercial: 0 to 70 °C Industrial: -40 to 85 °C Military: -55 to 125 °C I can understand the lower part (-40°C and -55°C) as these temperatures do exist in cold countries like…

Is circuit design based on min/max values good practice?

Time and again I am arguing with a colleague of mine about the question above. When I design a circuit for mass production (> 10k/a) I want to make it robust against every possible variation of component parameters that I know about. This means for…

Are there still practical modern uses for large through-hole resistors?

When teaching electronics to college students, we often use these large 1 W cylindrical resistors - not because we need the wattage rating, but because they are easy to handle and read the color code for students. This got me thinking: almost all…

ESP8266 - is it used in real industry?

I wonder if ESP8266 or similiar (ESP32 for example) modules are used often in real mass production in medical/automotive/military/households industries. I see many DIY projects with it, but there is a better alternative for mass production? If yes…

How do professional designs compensate for offset voltage in opamps?

I am new to electronics and have been told in class to always add precision potentiometers to compensate for input offset voltages in opamps for signal conditioning. My concern is that this offset voltage is inherent to the opamp IC and is different…

Is there a technical reason why sensors goes from 0.5 to 4.5V volts?

Is there a technical reason why sensors output goes from 0.5 to 4.5V (analog) or 10% - 90% (digital)? I understand that for diagnostic purpose one doesn't normally want to use the full range especially when sensor values are critical so that short…

Digital logic input with very wide input voltage range

We are developing an industrial controls product that will be used to monitor the presence or absence of voltage ranging from 5V to 480V. Since the unit will be generic and programmable, this input may be used in a variety of unpredictable…

How are terminal blocks depicted in a wiring diagram?

I have started to document the electrical system in a custom machine that we own. I'm using TinyCad for the schematic and that's working OK. I also want to create wiring diagrams to represent the routing of wires, which DIN rail they equipment they…

Why do vibration sensors use a negative voltage?

I've started looking at some industrial vibration monitoring sensors for a project and it seems like there's a number of brands that use negative outputs voltages. Many are eddy current sensors with specified supply voltages of -24 VDC and output…

What is a "current load" on a 24 V input used for?

The MAX14821 (datasheet) is a 24 V IO device that features selectable current loads for use in actuators on the inputs. What would this be used for? It's not just to load a 24 V "high" signal coming from a PNP-logic output, i.e. pull the input down…

Industrial equivalent of rapid prototyping hardware

If I want to automate something at home, I can use a Raspberry Pi or Arduino to hookup some sensors and put the business logic on the chip. Internet-of-Things-style, I can even read those sensors on my laptop. I sincerely hope Raspberries aren't…

Experimental determination of motor properties

There's a motor that I need to seek a replacement for but unfortunately the nameplate is no longer on it and it's been rewound already. While I can spec a new motor for the application, I'd consider this an academic exercise and I'd like to know if…
