The ALA5 incorporates an ATEX certified 4-20 mA load cell amplifier designed for operation within hazardous zones 0,1 & 2

The high performance ATEX 4-20 mA load cell amplifier provides 2-wire 4-20 mA current loop output and connects in-line for a range of signal conditioning for strain gauges, load cells, pressure and torque transducers. Intrinsically safe to EN60079-11 (previously EN 50020) standards.

The ALA5 can be connected to ATEX approved equipment within the hazardous zone or to non-approved ATEX equipment outside the hazardous zone provided that a suitable barrier is used.

Designed for fitting in-line to strain gauge sensors such as load cells, the amplifier is housed within a stainless steel IP67 NEMA 6 EMC protected enclosure and is supplied with 1m strain gauge cable and 5 m output cable.

An OEM option is available for customers wishing to embed the ATEX amplifier within a sensor. Please note: the ICA5ATEX is approved for incorporation into load cells and other enclosures. Please contact us to discuss your requirements.
