Yokogawa YTA70 Temperature
Transmitter
Yokogawa YTA70 Temperature Transmitter
Description
Like the YTA50, the YTA70 is a 2-wire
analog temperature transmitter that outputs a simple 4 to 20 mA output that
correspondes to the temperature measured. However, it adds HART® 5 (Code -E)
or selectable HART® 5 or HART® 7 (Code -J) digital communication.
The YTA70 delivers all the benefits found
in the YTA50 while adding HART® digital protocol communication. The HART®
protocol allows you to conveniently configue the transmitter using the latest
FDT/DTM technology. The YTA70 is the choice for all your control applications.
The YTA70 is a head mount type of
temperature transmitter that accepts thermocouple, RTD, ohms or DC milivolts
input and converts it to a 4 to 20 mA DC signal for transmission. The YTA70
conforms to the standard DIN form B head mounting. The YTA70 supports HART® communication
protocol.HART protocol revision is selectable from HART 5 orHART 7, and HART 7
features long tag number up to 32 characters, enhanced burst mode and eventnotification,
and command aggregation function.
