CS135 Ceilometer 2.4 Specifications 2.4.1 Measurement Specifications Maximum Reporting Range: 10 km / 32,800 ft Minimum Reporting Resolution: 5 m / 15 ft Hard Target Range Accuracy: +/- 0.25% +/- 4.6 m Reporting Cycle: 2 to 120s Cloud Layers Reported: Up to four layers reported, user selectable 2.4.2 Mechanical Specifications Height: 1000 mm Width: 330 mm Depth: 316 mm Total weight: 33 kg (excluding cables) Packed weight: 58 kg 2.4.3 Electrical Specifications Power required: Nominal 115 (106-137) or nominal 230 (216-253) VAC, 47-63 Hz, 470 W maximum in total. The hood heater requires a maximum of 270 W. The internal heater requires a maximum of 120 W. The supply voltage required is specified at the time of order. If it has to be changed later please contact Campbell Scientific for advice. Fuses: The power supply contains two fuses as follows: AUX fuse HBC 5 A (T) PSU fuse HBC 500mA (T) All fuses are 5 x 20 mm slow blow (T) and are the same for both 115 VAC and 230 VAC. Battery: Internal 12V 2Ah battery provides 1hr measurement without the blower/heater. The power supply is equipped with a system to prevent deep discharge of the battery. The CS135 uses Positive Temperature Coefficient (PTC) heaters within its design. These heaters are self-regulating, simplifying the internal design of the sensor and improving safety. Due to the nature of these devices the CS135 takes a higher current during start up. The CS135 will take up to 1 KW for the first few seconds of operation dropping off quickly to its normal operating power over a period of a minute. In cold environments the power consumption of the CS135 may be as high as 470 W. Also, in warmer environments it may be as low as 200 W. The heaters within the CS135 are purely resistive which will prove advantageous when connected to generators or when the power factor of your supply is important. 6

2.4.3
Electrical Specifications
Power required: Nominal 115 (106-137) or nominal 230 (216-253) VAC,
47-63 Hz, 470 W maximum in total.
The hood heater requires a maximum of 270 W.
The internal heater requires a maximum of 120 W.
The supply voltage required is specified at the time of order. If it has to be
changed later please contact Campbell Scientific for advice.
Fuses: The power supply contains two fuses as follows:
AUX fuse
HBC
5 A (T)
PSU fuse
HBC
500mA (T)
All fuses are 5 x 20 mm slow blow (T) and are the same for both 115 VAC and
230 VAC.
Battery: Internal 12V 2Ah battery provides 1hr measurement without the
blower/heater. The power supply is equipped with a system to prevent deep
discharge of the battery.
The CS135 uses Positive Temperature Coefficient (PTC) heaters within its design.
These heaters are self-regulating, simplifying the internal design of the sensor and
improving safety. Due to the nature of these devices the CS135 takes a higher
current during start up.
The CS135 will take up to 1 KW for the first few seconds of operation dropping
off quickly to its normal operating power over a period of a minute.
In cold environments the power consumption of the CS135 may be as high as
470 W. Also, in warmer environments it may be as low as 200 W.
The heaters within the CS135 are purely resistive which will prove advantageous
when connected to generators or when the power factor of your supply is
important.
