YOKOGAWA MC55 Pneumatic Indicating Controller

The Model MC55 Electronic Indicating Pressure Transmitters measure gauge, absolute, or compound pressure. The instruments transmit a proportional 4 to 20 mA DC signal over long distances using ordinary unshielded leads. The transmission distance is limited only by the load resistance.
