SUCO Pressure Transmitters Reliable in Tough Environments

SUCO Technologies developed its 063X series of pressure transmitters primarily for operation in CAN bus systems in mobile hydraulics.

The 0630 series support the CANopen protocol (according to CiA DS-301) with a data transmission rate of up to 1 Mbit/s, which has established itself as the standard especially in the automotive and automation industry. The 0631 series is based on the J1939 protocol (according to SAE J1939), which is mainly used in heavy commercial vehicles and mobile machines.

The pressure transmitters of the 063X series are designed for pressure ranges from 0 – 1 bar to 0 – 600 bar. Their stainless-steel housing 1.4301 / AISI 304 combines the advantageous material properties of analog transmitters with the advantages of digital transmission technology. The completely welded measuring cell made of stainless steel 1.4542 is particularly corrosion-resistant and guarantees media compatibility at temperatures from -40°C to +125°C.

The CAN bus transmitters with IP67 protection resist the shocks and vibrations common in mobile machines and industrial systems. The transmitters promise long-term stability and reliability with a service life of up to 107 pulsations.

SUCO offers the CAN J1939 pressure transmitter type 0631 as a preconfigured plug-and-play version that can be installed directly in the respective system without major effort. The CANopen transmitter type 0630 can either be specified with predefined values or according to customer requirements. In both cases, the values can be subsequently changed by the customer on site by using a CAN programming software.

SUCO’s pressure transmitters with CANopen protocol extend the possibilities of analog transmitters by numerous functions, such as the transmission of additional process and parameter data in real time (temperature, pressure values in various types, error messages, operating status, time stamp) or the setup of event-driven data transfers (events).

Both the CANopen and J1939 protocols enable interference-free serial data transmission, where transmission errors are reduced to a minimum due to numerous control mechanisms. Because of an integrated diagnostic function, interference signals and error sources can be quickly eliminated, increasing the system’s reliability.

In complex systems with many interfaces and long cable lengths, a CAN bus network can be used to reduce material, installation, and maintenance costs.
