Embedded loadcell for offshore! A first!

The BLH and Nobel Weighing Systems brands of Vishay Precision Group have released the LCAMP, a new embedded load cell transmitter for offshore applications.

The ATEX Ex ia IIC rated LCAMP transmitter is embedded in BLH and Nobel load cells. It is the industry's first such device that can be serviced and replaced in the field and that allows the transmitter and load cell to be replaced independently of each other without affecting system calibration. The unit output is two-wire 4 mA to 20 mA and supports HART protocol for calibration and system diagnostics of both the load cell and transmitter.

The LCAMP features a combined error rate of less than ±1% of RO, NAMUR compliant error signaling, an input voltage range of 10.5 V to 42 V DC, and IP 68 ingress protection when mounted in a load cell.

The unit is operational within a second from power-on. Fully-redundant units as well as other customizations are available.

The LCAMP connects through an M12 connector or a fixed-cable connection and is specified for operating temperature range of -40°C to +70°C.
