Description

Thanks to its compact size, exceptionally light weight, and easy-to-deploy mechanism, Tele-STTC is an ideal tool for measurement of areas that are difficult to access or for remote measurement of hot spots.

Tele-STTC supports ALARA principles by allowing the operator to obtain a reading far from the hot spot and limits the contact exposure to the radiation field.

Tele-STTC requires minimal room when packed (92 cm) and the pole can be extended up to 3.3 m (10.9 ft). The unit is so lightweight that even when unfolded, it doesn't need to be offset, and the pole and meter can be used together even for short range measurements. The meter remains at the user's eye level even when the pole is opened.

A shoulder strap is used to secure Tele-STTC when used in the open position or simply to keep it attached while being carried.

The unit consists of a detector integrated on a telescopic carbon fiber-based pole on which a meter is fixed by a connecting clip. The meter is removable and can therefore be used independently. Tele-STTC can be used with the Radiagem™ or Colibri personal survey meters, which are not included.

The detector integrated in the Tele-STTC is designed for gamma equivalent dose rate measurement. For instruments already integrating a compensated Geiger Mueller detector, this detector allows it to extend the instrument measurement range and to carry out remote measurements.

The detector is integrated in a compact and robust metal case which includes the Geiger Mueller detector, the high-voltage power supply and the pulse shaping circuits. It uses the time-to-count algorithm from CANBERRA, hence enabling a unique range of measurement with only one Geiger Mueller detector. By using only one detector, the Tele-STTC offers a better angular response than any other probe with an equivalent measurement range and comes in a smaller form factor.

The Tele-STTC is a CANBERRA SMART Probe (CSP™). It includes all key components of hardware circuitry (high-voltage power supply, amplifier, discriminator, etc.) Also, the intelligence associated with controlling those components is located in the probe - that is control and storage of key parameters, settings, calibrations, probe ID, alarm settings (10 values for each unit to display with default setting), etc. Thus the probe is a fully- integrated subsystem taking and transmitting the measurement to the instrument, which is used for display.

With high-voltage and digitization of the data occurring in the probe rather than the instrument, measurement quality is no longer dependent on external device quality (cable, host instrument). Moreover, a CSP is using a serial protocol to communicate with the host that can be an instrument or a PC.

Calibration and QA measurements can be performed directly with the probe, without even using any instrument, by connecting the probe to a computer with CANBERRA Smart Probe Software (CSPS™), allowing your instruments to remain deployed in the field.

Once calibrated, Tele-STTC is ready to be used as a ‘plug and play' probe to start a QA measurement in R/h, R, Sv/h, Sv depending on the connected meter.

The Tele-STTC is able to store up to 1000 data points from a data-logging procedure handled via the host instrument. These data are: Index, date/time, measurement value, selected unit and counting time.

Tele-STTC can be upgraded (probe's firmware) via CSPS, with the USB - PC cable and a PC. It is provided with a storage case. An adaptor is available to transform a Tele-STTC for Radiagem into a Tele-STTC for Colibri and vice versa hence minimizing the migration cost from one instrument to the other.
