I ran into a US made Ideal 61-337 DVM, which has a time limit of 1 minute for DC mA measurements:

The spec for Ethernet is a performance spec, in other words, for a given Ethernet speed, a 100m cable will support so many bits per second. That does not mean that the signal dies if the cable is 102m in length instead of 100.0 meters in length. The longer length means that the...

You don't provide identification of which instrument is in question, so "generic-isity" will have to apply. E&H Micropilot's radar level unit's manual at https://portal.endress.com/wa001/dla/5000619/7893/000/02/BA01121FEN_0316.pdf on page 101 lists F283 error as a high level, diagnostic...

I can only suggest checking to see if the part number on the card matches the hazardous service rating of the positioner and checking to see that the ribbon cable is connected in the right position on AOM card.

> signal feedback is full different from actual value of valve > feedback signal not change until the valve varies It is impossible to know what is actually occurring without details. 1. Can you give some numerical examples of what the position of the valve is, compared to what the feedback...

Normally the Analog Output Module, AOM, module just works, there are no parameters needed to configure it. 1. Several different option cards share the same slot. Are you sure the module is an analog output module (either 6DR4004-8J or -6J? 2. The AOM card needs data from the positioner...

The Siemens PS2 uses terminals 61 (+) and 62 (-) for the 4-20mA 2-wire, loop powered analog output. Is that the same on your Arca positioner?

> that other USB serial adapters don't offer ? Generic USB/serial adapters that are not specifically designed with firmware to handle Modbus will have problems with Modbus RTU because of timing delay issues after the packet is finished. Gateways and adapters should be chosen for stated...

>Is there a one stop place I can go to learn about all of these standards, how they work, how to test these protocols? Not that I know of > RS-422,RS-232, RS-485 These are serial hardware busses. Busses are electrical in nature and just carry bits. Big item is RS-232 is point-to-point...

The quoted text is confusing. Is there an object under test in whatever process/scheme is going on here? Is the "glass bulb or fusible element" an object that is being tested in the heated liquid solution? A "glass bulb" might possibly refer to a certified liquid-in-glass thermometer a...

I can't help for that product.

Control Edge Builder for which product, the RTU, the PLC or the HC900?

A bare, uninsulated (exposed wires) junction is the fastest responding thermocouple junction but a bare junction is subject to a ground loop if the object that the thermocouple touches is at a potential different than the 'ground' potential of the measuring circuit. I suspect that the ground...

Heaters consist of nichrome resistance wire in a sheath packed with a white powder, normally magnesium oxide, an insulator, and a termination at the opening. Those spiral heaters start out as straight heating rod elements that are bent to shape. You can make mild bends in small diameter...

Yeah, the cosmic ray thing. It's that fall back position for "who knows why it failed?". Blame it on cosmic rays. It wouldn't be a programming bug that never accounted for a cold start in the absence of a valid persistent direction variable, which maybe was battery-backed with a dead battery?

The heater in the diagram appears to be a spiral shape heater. Google spiral heater elements. You need to know the line voltage driving the element, and the wattage needed. Size wise it's gotta fit your vessel. ±1°C might be a challenge if you have to get a certified calibration on the...

I assume that the 300°C is a typo (95°C?), because that rig is not a pressure vessel. The RTD should be a 3-wire RTD because the measuring device should be able to actively compensate for lead wire resistance, which is not the case with 2-wire RTDs. However, I have run across some 1/16 DIN...

What is stopping the solutions you've already discovered from being useful?

No idea what pressure you're dealing with. A direct acting electrical solenoid valve requires no differential like a pilot operated electrical solenoid valve does. Something like a direct acting solenoid like an ASCO 8262 series. A pressure gauge does not need a high Cv because there's...

Probably through-hole single layer PC boards, DIP chips, maybe some socketed PROMs? All linear DC power supplies? Does it have ribbon cables (which I despise)?
