Kotron® Sentinel Models 822, 832 and 842 RF Point Level Switches DESCRIPTION The Sentinel is a powerful multi-point level switch. The microprocessor-based circuitry has non-volatile memory, to protect against data loss. Powerful diagnostics check all major aspects of the system while MagneCal™ offers the user the advantage that one small level change is needed to calibrate. FEATURES • Optional intrinsically safe probe circuitry (with on-board barriers) allows safe use, even with bare probes in hazardous media • Intrinsically safe remote mount models up to 800 feet (240 meters) of cable • Integral or standard remote mount up to 2500 feet (760 meters) for application flexibility • Two to four DPDT relays yield wide application flexibility for most alarm and control operation • Relays 2 and 3, Series 832/842 models, may be used for lead/lag pump sequencing • Time delay eliminates relay chatter due to turbulence. • Usable with all Kotron probes for excellent application flexibility • 3-button/4-digit LED data entry of all parameters • One small level change (2% of span) needed for initial calibration in most cases • Powerful self-diagnostics check the system, minimizing the need for routine maintenance checks • Diagnostics check the integrity of the probe • One relay may be dedicated as a diagnostic alarm APPLICATIONS • Hydrocarbons and solvents • Corrosives • High temperature/pressure liquids • Multi-point alarm/control • Pump control • Lead/Lag pump control • Process temperatures up to +1000° F • Process pressures up to 5000 psig TECHNOLOGY The amount of capacitance developed in any vessel is determined by the size (surface area) of the probe, the distance from the probe to its ground reference, and the dielectric constant of the medium being measured. Considering that the probe’s mounting position is fixed and the dielectric of the medium is constant, then the amount of capacitance developed in any vessel becomes dependent upon the amount of the probe which is covered by the media. As the media rises and falls in the tank, the amount of capacitance developed between the probe and the ground reference also changes. The capacitance signal is converted to a frequency proportional to the change in level. The amplifier then converts this digital signal into an isolated 4–20 mA analog output signal.

To better understand how this calibration is achieved, consider the approach in two steps: High level alarm Probe can be calibrated in one level change and level movement as little as 2% of tank height Pump #2 Pump #1 Low level alarm Step 1 Probe calibration All RF Capacitance devices must be calibrated in the process vessel. To calibrate, the process level must be varied to achieve a capacitance change. With MagneCal, the probe is calibrated by establishing only two reference points and storing the data in the microprocessor, via the 4-digit LED and 3-button keypad. With conventional electronics, the level would need to be varied multiple times. Step 2 Relay configuration The relays are now configured with no further level change required. The Sentinel draws upon the reference data stored during the probe calibration. The relay control points are easily entered via the same 4-digit LED and 3-button keypad. All relays can be calibrated and recalibrated without further level change. Relays can be set up for lead/lag operation to enable even pump wear. 3 AGENCY Agency FM APPROVALS Protection Method Explosion proof Area Classification Class I Div. 1, Groups C & D Class II Div. 1, Groups E, F & G NEMA 4X, IP65 Electronics: Class I Div. 1, Groups C & D Class II Div. 1, Groups E, F & G NEMA 4X, IP65 Probe: Class I, II, III, Div. 1, Groups A, B, C, D, E, F & G NEMA 4X, IP65 Approved Model 8X2-1X02-G0X 8X2-1X03-G0X with rigid insulated probe 8X2-1X05-G0X 8X2-1X06-G0X Explosion proof with intrinsically safe probe circuit 8X2-1X02-R0X 8X2-1X03-R0X 8X2-1X03-Y0X with rigid insulated probe 8X2-1X05-R0X 8X2-1X06-R0X 8X2-1X06-Y0X Explosion proof Class I Div. 1, Groups B, C & D Class II Div. 1, Groups E, F & G NEMA 4X, IP65 Electronics: Class I, Div. 1, Groups B, C & D Class II, Div. 1, Groups E, F & G NEMA 4X, IP65 Probe: Class I, II, III, Div. 1, Groups A, B, C, D, E, F & G NEMA 4X, IP65 Explosion proof with intrinsically safe probe circuit CSA 8X2-1X00-C00 8X2-1X01-C00 8X2-1X02-G0X 8X2-1X03-G0X with rigid insulated probe 8X2-1X05-G0X 8X2-1X06-G0X Non-hazardous Explosion proof TYPE 4X Class I Div. 1, Groups C & D Class II Div. 1, Groups E, F & G TYPE 4X Electronics: Class I Div. 1, Groups C & D Class II Div. 1, Groups E, F, G TYPE 4X Probe: Class I, II, III, Div. 1, Groups A, B, C, D, E, F & G TYPE 4X Explosion proof with intrinsically safe probe circuit 8X2-1X02-R0X 8X2-1X03-R0X 8X2-1X03-Y0X with rigid insulated probe 8X2-1XX5-R0X 8X2-1XX6-R0X 8X2-1XX6-Y0X Explosion proof Class I Div. 1, Groups B, C & D Class II Div. 1, Groups E, F & G TYPE 4X Electronics: Class I Div. 1, Groups B, C & D Class II Div. 1, Groups E, F, G TYPE 4X Probe: Class I, II, III, Div. 1, Groups A, B, C, D, E, F & G TYPE 4X Explosion proof with intrinsically safe probe circuit 4 MODEL NUMBER Models available for quick shipment, usually within one week after factory receipt of a complete purchase order, through the Expedite Ship Plan (ESP).
