Ordering Information

Tipping Bucket Raingages

Recommended cable length is 25 ft, but many customers will order

a 50-ft cable to place the gage away from the tower or tripod.

TB4-L

Tipping bucket with thermoplastic base and 0.01-in.

tips. Enter cable length (in feet) after the -L. Must

choose a cable termination option (see below).

TB4MM-L

Tipping bucket with thermoplastic base and 0.2-mm

tips. Enter cable length (in feet) after the -L. Must

choose a cable termination option (see below).

CS700-L

Tipping bucket with aluminum base and 0.01-in. tips.

Enter cable length (in feet) after the -L. Must choose

a cable termination option (see below).

tips. Enter signal cable length (in feet) after the -L

and enter the power-cable length after the -LP. Must

choose a power supply option (see below).

Cable Termination Options for

non-heated raingages (choose one)

-PT

Cable terminates in stripped and tinned leads for

direct connection to a datalogger’s terminals.

-PW

Cable terminates in a connector for attachment to

a prewired enclosure.

-CWS

TB4/TB4MM cable terminates in a connector for

attachment to a CWS900 interface. Connection to

a CWS900 interface allows the TB4 or TB4MM to be

used in a wireless sensor network. This option is

only for the TB4 and TB4MM.

Power Supply Options for CS700H (choose one)

-AC

AC used to power the CS700H’s heater. Includes

a Phoenix Contact power supply that provides

dependable power to the CS700H and other

Campbell Scientific components in cold climates.

-DC

User-supplied batteries power the heater. This option

is for remote areas using wind or solar power to

recharge the batteries. Required battery capacity

varies according to site location and application.

Phoenix Contact Power Supply (CS700H-AC only)**

Model Name:

Quint-PS/1AC/24DC/10

AC Input Voltage Range:

85 Vac to 264 Vac

Power Consumption

120 Vac:

~2.77 A

230 Vac:

~1.24 A

Protective Circuitry:

Transient Surge Protection Varistor

Integrated Input Fuse:

6.3 A (slow blow, internal)

Normal Output Voltage:

24 Vdc ±1%

*If you assume four 10-hr snow storms in a week, then the average weekly energy consumption is 4 x 10 x 45 W = 1800 Whr/week; the average

amp hours over one week are 4 x 10 x 3.7 A = 150 Ahrs; and the amps averaged over a week are 150 Ahrs / (24 x 7) = 0.9 A.
