Sampling probe

The standard probe is fitted with a DIN flange DN 65, PN 6. The probe is provided with a regulated heater, and has a power consumption of 400 VA. It is supplied with a weather protection hood and 2 µm filter. The maximum dust concentration at the sampling point should not exceed 2 g/m . The sampling pipe is 1 000 mm long, is made of stainless steel, and has dimensions of 20 x 1.5 mm. The sample gas temperature must not exceed 600 °C.

It is also possible to purchase the Set CEM 1 without sample probe.

Heated sample gas line

The temperature of the heated line is regulated at 200 °C by a temperature controller. The power consumption is 100 VA per meter. The internal core is made of PTFE 4/6. The heated line can be up to 35 m in length. Lengths greater than 35 m can be provided upon special request. If desired, the system can also be supplied without a heated sample gas line.

Mounting frame

The basis of each CEM 1 set is the mounting frame with hinged frame (40 HU) for installation of up to five 19" rack units. The mounting frame includes a standardized sample preparation system designed for an ULTRAMAT 23.

The sample preparation system includes a 3/2-way solenoid valve, 3-way switchover ball valve, regulating valve, corrosion-resistant sample gas pump (power consumption 60 VA), condensation trap, room air suction filter with filter element, LOGO for digital display of individual signals in the cabinet, 24 V DC power supply unit (power consumption 70 VA). Also included are a sample gas cooler (power consumption 200 VA) with integral preliminary condensation trap, heat exchanger, hose pump, moisture sensor with flow cell and Teflon filter. Teflon tubes connect the components.

The external dimensions without plinth are 2 000 x 800 x 800 mm (H x W x D). A cabinet depth of 600 mm is also optionally available (not suitable for LDS 6). Hoses and cables can be connected from the left or right. A distance of 500 mm must be provided on the left or right at the installation site for introduction of the hoses and cables.

In addition to the sheet-steel mounting frames for indoor installation, an FRP version is also available for outdoor use. The FRP cabinet is always provided complete with side panels and plinth. The external dimensions are 2 080 x 800 x 600 mm (H x W x D). The GRP cabinet cannot be combined with the LDS 6.

Preparation of sample preparation system for second ULTRAMAT 23

The standard system with sample preparation system and electronics is prepared for one ULTRAMAT 23. If a second ULTRAMAT 23 is to be fitted, this option must be selected so that the sample preparation system and electronics are extended accordingly.

Additional filter

In addition to the fine filter and moisture filter which are always present, a coalescence filter can be optionally fitted in the sample preparation system.

Side panels with doors

Optional outer panels can be selected for the sheet-steel mounting frames. This possibility allows use of the CEM 1 set in analysis cabinets as a rack design on one hand, or on the other as a cabinet design in halls requiring degree of protection IP54. Either a sheet-steel door without window or a glass door can be selected.

Plinth

Plinths with a height of 100 and 200 mm are additionally available.

Cabinet cooling and ventilation

Optionally available are a fan with outlet filter, an air-conditioning unit for indoor installation, and an air-conditioning unit for outdoor installation. The system can be ordered without a fan or air-conditioning unit if the side panels and the door with window are omitted.

The fan with outlet filter has a power consumption of 60 VA, and is fitted in the cabinet wall. The delivery also includes a thermostat with a power consumption of 25 VA.

The air-conditioning unit has a cooling power of 820 VA.

A 19 liter condensation bottle can be provided as an option. It is also possible to order the system without a condensation bottle if the condensation can be removed on-site.

NO₂/NO converter

The mounting frame and cabinets can be optionally extended by a 19" rack unit with NO₂/NO converter with carbon cartridge. The power consumption is 520 VA. The flow rate is 90 l/h. An NO₂/NO converter is required if the share of NO₂ in the total NOx is greater than 5% and/or if total NOx is to be always determined.

Power supply

The system can be designed either for 115 V AC, 230 V AC or 400 V AC (-15 %, +10 %) with 50 or 60 Hz.

Three phases, neutral and ground must be provided by the customer at 400 V AC.

Analog signal processing

As standard, the analog signals are simply connected to isolating terminals. As an option, the analog signals can be processed twice without electrical isolation by a diode module, or twice with electrical isolation.
