Meters

Honeywell’s Series STT250 Temperature Transmitters can be supplied with local or remote indication. An Analogue or Smart meter can be mounted integral to the transmitter inside the field mount housing. Order an integral meter as part of the model number; Table II _ _ M and _ _ S, respectively. Order a remote meter as model RMA300.

The analogue meter is a 4-20mA moving coil type and displays the temperature in 0 to 100% span.

The Smart meter accepts 4-20mA or DE protocol and displays temperature on a LCD in engineering units or 0 to

100% span. The Smart meter displays temperature in 0 to 100% span with the STT25H HART unit. Refer to 34-ST- 25-08D for more details.

The remote digital meter reads DE protocol and displays temperature on a LCD in 0 to 100% span. Refer to 34-ST-25- 07A for details.
