Frequently Asked Questions

Class A or Class B — which do I need?

Class B (±0.3 °C at 0 °C) suits most industrial loops; Class A (±0.15 °C) is for custody, laboratory or high-accuracy duty.

Can it be delivered with a transmitter?

Yes — the YYBY100 head-mounted transmitter turns it into a 4-20 mA loop in one unit.

Is a thermowell available?

Yes — stainless and special-alloy thermowells are manufactured to your process dimensions.
