Wireless communication is emerging technology from the office world to the industrial world. It is important that this technique are applied by the users in industrial environments because the industrial communication underlies stricter conditions than office communication. In this paper, It has been designed and implemented wireless adapter interface module with gateway connected to 4-20 mA devices and the Differential Pressure (DP) transmitter is considered. The implemented system consists from wireless adapter connected to the DP transmitter and the gateway device that used as a link between the field devices and the host. The standard method deals with a two-way or bidirectional communication protocol, which eliminate the drawbacks of 4 to 20 mA standard signal in the industrial measurements that can be only transmitted or measured one parameter value. With developed method, an additional information can be transmitted using wireless signal based on frequency shift keying modulation. In addition, the system design has been implemented and proposed various configurations for field device connections. The experiment results are presenting to verify the success of the implemented system.
