HNL INSTRUMENTS 800

Pushbutton calibration of set points enables calibration on site without tools.
Programmable switching delays - the switching on or off (or both) of the relays may be delayed from 0.5 seconds to 15 minutes. This is particularly useful for preventing unwanted switching due to pressure transients.
Display of Maximum and Minimum pressures recorded by the Smartstat.
Display of transmitter output in mA.
Displayed units of measurement - can be changed by the user as required.
Single point local annunciator option - one relay is used for a local alarm and the second for remote transmission of alarm. The second relay can be configured for manual or auto reset.

24vdc supply, 4-20ma loop powered

Standard electrical and i.s. Certified versions available
Reduce costs

Very high (or low) pressures.
High accuracy and repeatability.
Very large (or small) switching differentials.
Pressure ranges from -1 to 1000 bar
Dp ranges from 15 mbar to 4 bar

The Series 800 Smartstat is a microprocessor controlled pressure switch, transmitter and indicator, which enables several instruments to be replaced with a single device.
There are some pressure and differential pressure (DP) switching applications that are very demanding due to the need for :-Very high (or low) pressures, high accuracy and repeatability, very large (or small) switching differentials. These requirements may exceed the capabilities of conventional mechanical pressure switches, the Smartstat was designed to overcome these problems.
The Smartstat is available with pressure ranges from 100 mBar to 1000 Bar, and DP ranges from 15 mBar to 4 Bar providing a typical accuracy of 0.1%.
Two independent single-pole, double-throw (SPDT) relays are fitted in the Smartstat, the operating points of which can be set anywhere within the range. The switching differential can be set from 0.1% to 100.0% of range without loss of accuracy.

SUBSTANTIAL COST SAVINGS
Replacing a transmitter, switches and a gauge with a single Smartstat reduces equipment costs. Additionally there are reductions in documentation, installation time/ fittings/cabling, and calibration/maintenance costs.
