Electronic Pressure Sensor with Radio Transmission

Electronic Pressure Sensor with Radio Transmission - ROEMHELD F9.750

• Battery-powered pressure sensor with radio transmission
• Long-field range: max. 300 m
• Code class: IP67
• Receiver unit with antenna
• Voltage: 20..30 VDC
• Outputs: 4x analog or 2x analog + 2 relay
• Data interface: RS485 Modbus

Application:

Electronic pressure sensors with radio transmission will be used to monitor hydraulic clamping fixtures, if:

• Hard wired connections are not possible or too expensive
• The pressure has to be measured in hard-toreach points or has to be adjusted frequently
• The pressure has to be measured continuously in several places at the same time
• The pressure has to be checked during start up and maintenance with minimum installation costs
  In general, these are moving or rotating systems.

Typical applications are:

• Automatic manufacturing systems
• Transfer lines
• Assembly lines
• Rotary indexing fixtures
• Rotary indexing tables Up to 16 pressure sensors can be individually configured and monitored at a stationary receiver unit with antenna.

Description:

ROEMHELD Electronic Pressure Sensor with Radio Transmission [F9.750] operates according to the DMS principle. The measured values are sent in the ISM band to the stationary receiver unit. The replaceable lithium battery has a service life up to one year and the state of charge is constantly monitored.
The receiver unit can be configured with the keyboard and the two-line LCD-display, with the optionally available setup program on a PC or laptop that can be connected with a USB cable it is even more flexible. A laptop with the loaded setup program can be directly connected to the pressure sensor by means of a mini-USB cable. Thus, a temporary pressure measurement is also possible without receiver unit, e.g. during start up and maintenance.
The receiver unit has four freely configurable analog outputs (optionally two relay outputs) and an RS485 interface with Modbus protocol. Available as a accessory is a Profibus gateway that translates the Modbus protocol into a PROFIBUS protocol with GSD
