The OTM-DRUM has been designed for the detection and measurement of gamma radiation on potentially exposed tools and objects.

It includes four 100 x 50 x 5 cm and two 50 x 50 x 5 cm plastic scintillator detectors with PMT and six HV sources. This guarantees that the detectors perform in their optimum operating conditions, providing and excellent signal output.

HSS has designed and manufactured the OTM series for end user’s with different purposes: nuclear safety, R&D, etc.

More than 40 years of experience delivering high quality products demonstrates our commitment with our customers satisfaction.

Usability

An user friendly display guides the user through all the equipment configuration menu.

All the recorded data is stored and managed by system, making possible to export it via USB.

Calibration of the equipment can be easily performed following the system instructions.

The software is 100% configurable according to user’s requirements.

Stability

The equipment is shielded with a 20 mm lead sheet to minimize the background contribution.

In case of high background environments, the lead shielding can be incremented.

Stability and durability are provided by means of an aluminium structure and the steel cover plates.

Detectors

Each detector’s operating parameters can be customized individually.

The counting measure is displayed showing the information provided by each detector, making possible to asses the contaminated area.

The equipment monitors the background constantly and starts the operation when an object is detected inside the counting chamber.

Alarms and threshold can be easily set depending on user’s requirements. This includes high and low background alarm, high counting alarm, etc.

An audio interface provide instructions and status update to the user. Male or female voice can be selected.

A roller conveyor can be installed as an optional to help the user to introduce the drums inside the equipment.

The required power supply can be customized: 220 VAC / 110 VAC.

Optional detectors like NaI, LaBr3 or CZT can be included in the design to obtain high quality spectrums.

The total weight, including 20 mm of lead shielding, is approximately 5000 kg.

The external dimensions are 170 x 95 x 95 cm (H x D x W) approx.
