3-Channel

FairfieldNodal ZLand 3-Channel Sensor

The FairfieldNodal ZLand 3C is a compact all-in-one 3-channel sensor & datalogger with onboard GPS timing, and a self contained power supply. Originally designed for use in large N industry deployments, it has been adopted by the academic community as a useful sensor for both active and short-term passive deployments.

Unlike other sensors & dataloggers at PASSCAL, use of the ZLand 3C requires a deployment plan to be filed in advance with PASSCAL for sensor and handheld unit pre-programming.  Likewise, the units must be sent back to PASSCAL for data offload.

Dataloggers

A datalogger (also know as data acquisition system or DAS) is piece of electronic equipment which converts an input into a digital time series representation. Immense care should be taken when setting up and programming a datalogger. It is highly recommended that only experienced users program their own dataloggers and all others should consult a PASSCAL staff member for assistance.

While specific procedures and programming details will vary between the various types of dataloggers, there are several things that hold true when working with any datalogger.

The datalogger should be:

3-Channel Dataloggers

Quanterra Q330

Q330's are typically used for broadband standalone and telemetered real-time data recording. They have an external storage device (either hard drive or USB flash drive) and lend themselves for a variety of telemetered modes.

 

Reftek RT130

Quanterra Q330

The Q330 is a 3 or 6 channel high resolution datalogger. It is low power and highly configurable for a wide range of applications and sensors. The Q330 is housed in a sealed aluminum enclosure which makes it highly resistant to the environment. Telemetry is a main focus of the Q330, but it also has a robust on-site data storage system which uses external Balers. This makes it easy to swap out the data storage on-site for when servicing doesn't allow an extended visit. The Q330 can write data to four different receiving systems simultaneously. It also has built-in sensor controls, an automatic mass recentering feature, and calibration functions. The Q330 is programmed with a Windows program called Willard, it can also be controlled by a PalmOS program for when working in the field.

RefTek RT 130 Datalogger

The RT130 is a 3 or 6 channel high resolution datalogger. It is low power and highly configurable for a wide range of applications and sensors. It is housed in a plastic clamshell-style enclosure which is nearly waterproof and has internal data storage in the form of two compact flash cards. The RT130 can simultaneously record to the CF cards and transmit data in near-realtime using either ethernet or serial based telemetry. It has built-in sensor controls, scheduled mass recentering, and calibration functions. The RT130 is programmed with a PalmOS program called PFC-130 via the serial port.
