Re: Tri-clamp Float Switch of Choice

Did you buy some TTI clamp floats? If so, source?

Re: Tri-clamp Float Switch of Choice

I use 3 cheap ones in series so if one switches on, the DIN is made. They are over the side so I have no idea what others are using

Re: Keyence Process Sensors

If using a DIN no BCS Ground is needed. 24 vdc + to VCC 24 vdc - to GND 24vdc Trigger to in (Trigger). From your flow thing 5 vdc + to common out and NO to DIN. When relay is activated, it allows 5 vdc + to go to pull down resistor inside the BCS. Make that DIN. One shot. You will need a method ( to...

Re: Keyence Process Sensors

Just looked at specs again and that one has both operating voltage and trigger of 24 vdc. You would still need to provide the 5 vdc (BCS 460/462) or 12 Vic (BCS 482)

Re: Keyence Process Sensors

That relay might work. You have 3 voltages when using a relay. The first is the operating voltage of the relay. This one is 24 because. That is the PowerPoint cause the relay to switch. The next is the trigger voltage. This can be a range but 3-5 vdc triggers are most common. The last is the rating ...

Re: Keyence Process Sensors

4-20 ma is vaporware on the BCS. Would be nice but you only have high input or output control with a BCS. I use DINs to control the flow of the processes. From your description, it seems this is similar to what a float switch, just based on flow. I have had success by Measuring “time” for volume as ...

Re: Keyence Process Sensors

You could use a Relay board or Resistors to regulate the voltage to 5 v+ (BCS 460/2) or 12 v+ (BCS 482). I would use a relay board. You could then signal a DIN or an Output. You could use a buck transformer as well. This one would work for both a BCS 460/2 or 482 as it can change 24v to both 5v and ...

Re: BCS460 bad Temp 1 ??

1. Swap probes

If Temp 1 is still high, check coefficients and wiring.

If issue follows probe , probe or wiring on that probe is bad

I have had probes where the heat has ruined the probe wiring just where it goes in the jacket (propane burners).

I now use a heat sleeve
