Since the temperature at the site reaches up to 100°C, it has been confirmed with the manufacturer of the locator that it may not be able to withstand such conditions. What would be the effect of using an integrated sealing system with an air-cooling circuit? The locator works fine in an environment of 80°C!

We set up a fan to blow air; that’s how we do it

In this case, a split potentiometer can be used; it is more reliable and energy-efficient than air cooling

Are there separate valve positioners?
