HLS 330D Intelligent Level Transmitter Features
Precision Digital Hydrostatic Measurement
Intelligent digital processing provides active temperature compensation and linearisation, enabling accuracy of up to ±0.1% of span according to EN IEC 62828-2.Flush Diaphragm Process Connection
The G 3/4 inch DIN 3852 process connection has a flush diaphragm arrangement for compatible liquid level measurement duties.Configurable Damping Offset And Span
With the appropriate interface and software, electronic damping is adjustable from 0 to 100 seconds, offset from 0 to 90% of span and span turn down up to 10:1.Broad Hydrostatic Level Measurement Capability
Nominal level ranges from 0 to 4 mH₂O to 0 to 400 mH₂O support installations from shallow vessels to higher pressure level applications.Consistent Accuracy Through Turn Down
Accuracy does not change at turn down up to 5:1. At higher turn down, the stated accuracy calculation allows the selected range to be assessed for the required operating span.Analogue Output And Interface Options
The transmitter is available with a 4 to 20 mA two wire output or a 0 to 10 V three wire output. Communication interface options require a seven pin Binder Series 723 connection.Stainless Steel Process Construction
The pressure port and housing are stainless steel 1.4404, equivalent to 316L, and the diaphragm is stainless steel 1.4435, equivalent to 316L. FKM is the standard seal material.Safety And Connection Flexibility
Ex ia intrinsic safety versions are available for 4 to 20 mA two wire units, with electrical connection options including ISO 4400, Binder, M12, field housing, cable gland and ventilated cable outlet arrangements.
