Commonly refer to as “Hockey Pucks” due to their shape, head-mount temperature are small disc shaped transmitters that are often mounted within a connection head. The connection head is usually attached directly to the sensor; but, can be located remotely. There are several different styles on the market. Yokogawa’s head-mount transmitters are DIN B compliant. The DIN B defines the general dimensions of the transmitter.
YTA70 temperature transmitter
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.
