Cycle Time

4 to 8 Minutes Typical

Analogue Output

4 off 4-20mA fully isolated. Maximum Load Impedance 7000

Serial Output

Modbus RTU Over RS485 As Standard. All alarms, remote calibration and remote standby are available over Modbus. Full remote operation over LAN, Ethernet hardwired or via fibre optic cable are available as an option. Other protocols are available on request.

Alarm Contacts

2 sets of C/O voltage free alarm contacts rated 0.5A @ 250Vac and 1A @ 24Vdc are provided to notify common warning or fatal alarms.

Contact Inputs

The Cloud Point can monitor 4 off customer external contacts (minimum rating 24V, 0.1A) These may be named by the customer and allocated into the warning or fatal alarm groups as required.

Mounting

Free standing as standard, wall mount frame option available.

Sample Pressure

0.5 to 2.5 barg

Sample Temperature

At least 14°C above the expected/last Cloud Point (User Configurable). Maximum 60°C. Sample temperature is continually monitored and sample is isolated if its temperature is too high.

Sample Flow (Normal Operation)

20 to 60 L/Hr free of dissolved water and entrained solids. Sample flow through analyser cell is continuously monitored

Sample Flow (Calibration)

Typically 1 to 2 litres per calibration cycle.

Sample Disposal

The analyser sample outlet must be connected to an atmospheric drain or sample recovery unit

Analyser Vent

The analyser vapour vent must be connected to atmosphere

Power Supply

100-240Vac 50/60Hz Maximum Load 500VA (Auto Sensing)

Instrument Air

Between 4 to 10 barg, dew point less than -20°C, flow 100 L/Min

Coolant Flow

Typically 30 L/Hr at a pressure of 5 barg maximum

Coolant Temperature

Depends upon cloud point. Typically a 50°C differential should exist between coolant temperature and lowest measurable cloud point. Coolant may be water, chilled glycol and water mix or the sample itself. Coolant temperature id constantly monitored.
