ROTOTHERM - SENTINEL RECORDER

The Sentinel range of microprocessor-based circular chart recorders combines the simplicity and clarity of pen drawn traces together with the versatility of microprocessor control.

Each channel is equipped with a universal signal input which is compatible with all industry standard sensors and signals including thermocouple types J, K, T, E, N, R, S and B, Pt100 platinum resistance temperature detectors and 4.20mA current loops.

Simple installation and effortless operation are attributes of the Sentinel range, assuring precise measurements through the use of multislope, integrating analogue to digital converters with 16-bit resolution which sample the input every 0.5 seconds.

ROTOTHERM - DIGIGAUGE

High accuracy and a 4 digit display enables the DigiGauge to be used as a standard test gauge, replacing less accurate, sometimes fragile analogue test gauges. Factory calibration certificates traceable to National Standards are provided and NAMAS calibration certificates can be supplied if required.

Covering a wide range of test and measurement applications with pressure ranges available from vacuum to 400 bar, DigiGauge can be supplied with hygienic fittings for food applications or with diaphragm seals for use on corrosive, viscous or crystallising fluids.

DigiGauge can be supplied with two pressure units, bar and psi - the required measurement unit being selected by an internal switch. The first pressure unit defines the actual range of the instrument, the second pressure unit provides an equivalent scale. Custom calibrations can be applied to enable indication of tank / vessel contents displayed in any units of your choice, a drawing of the tank will be required at the time of order placement. All standard DigiGauges are calibrated to traceable standards. Temperature compensated sensors may be specified to automatically correct zero and span drift.

Non-intrinsically Safe versions of DigiGauge can also be specified with a MAXIMUM and MINIMUM pressure logging option. DigiGauge is powered by 2 standard 1.5V AA cells.
