STTC Wide Range Gamma Probe

Features

• Measurement of H*(10) ambient gamma dose equivalent rate
• Energy compensated Geiger Mueller detector
• Gamma dose rate measurement from 0.3 ìSv/h to 10 Sv/h (30 ìR/h to 1000 R/h)

Description

The STTC probe is designed for gamma equivalent dose rate measurement. It can be connected to any CSP™ survey meter with the appropriate cable.

For instruments already integrating a compensated Geiger Mueller detector, this probe extends the instrument measurement range and supports remote measurements up to 30 m (98 ft).

The STTC has a compact and robust metal case which includes the Geiger Mueller detector, the high-voltage power supply and the pulse shaping circuits.

The STTC uses the Time-to-Count algorithm from CANBERRA, enabling a unique range of measurement with only one Geiger Mueller detector. By using only one detector, the STTC offers a better angular response than any other probe with an equivalent measurement range.

The STTC is part of CANBERRA’s new SMART Probe (CSP) family. 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 communicating the measurement to the instrument.

With high voltage and acquisition 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, 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 survey meter. STTC connects to CSP survey meter via a 1.5 meter or 20 m CSP cable.

The STTC probe 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.

STTC’s firmware can be upgraded via CSPS, a USB cable and a PC.

STTC is also available in Tele STTC version which integrates the probe in a pole. See Tele STTC documentation for more details.
