Pressure Transmitter digital DCT 541 (RS485 Modbus RTU)
Item number: DCT 541 Applications Environmental & Energy technology
Price on request
Delivery time:Delivery time on request
The industrial pressure transmitter DCT 541 was especially developed for hydrogen applications and can also be used with other technical gases (e.g. oxygen) and uses the communication protocol Modbus RTU which has found the way in industrial communication as an open protocol. The Modbus protocol is based on a master slave architecture with which up to 247 slaves can be requested by a master.
For hydrogen applications, it is important to use a material that minimizes or prevents hydrogen embrittlement due to its chemical properties.
For oxygen applications, the special cleaning and manufacturing process ensures that residual particles and hydrocarbons are minimized and no reaction can occur during production.
