Q&A

Cryogenic fluids?: Application of Thin Film is not applicable due to the extremely cold nature of the cyrogenic fluids and associated systems.

What about the cold environment applications?: Temperatures above 0℃ for both the Thin Film sensor and Pulsar Scope are acceptable.

High humidity?: Both the Thin Film and Pulsar Scopes can operate in high-humidity environments; however, the it is recommeded that the non-explosion proof Pulsar Scope be protected from potential condensation.

What is the length of the Thin Film sensor cable?: It is recommended 20 m or less for temperatures below 100℃, and 15 m or less for temperatures above 100℃ and below 200℃.

How many sensors can a Pulsar Scope measure?: Up to 8 sensors can be measured simultaneously with one Pulsar Scope (non-explosion-proof/explosion-proof).

Power requirements?: Traditional dry-type batteries are utilized. For the non-explosion-proof Pulsar Scope, 4 AA batteries are necessary, whereas, the explosion-proof version uses only 2 AA batteries (Mitsubishi designated products).

What is the radio communication distance of the pulsar scope?: The non-explosion proof Pulsar Scope can communicate at 400 m with no obstacles (line-of-sight), whereas, the explosion proof version is limited to 200 m. However, the communication distance will vary depending on the quantity, type, and general area conditions. Ensuring that the placement of the Pulsar Scope is positioned appropriately for data acquisition will minimize communiction issues.

Can the existing flaw detector be used for the Thin Film sensors?: Use use of 3rd party flaw detectors is possible; however, understanding the environment where the Thin Film sensors and detector will be installed is essential, e.g., explosive/combustible areas. Measurment data from Thin Film sensors can to acquired from 3rd party detectors which are compatible with a single-oscillation probe (applied voltage of 100 V or more, and a device compatible with a probe frequency of 8.5 MHz).

What are the specifications of the Thin Film sensor?: The applied voltage is 100 V or more, ultrasonic center frequency is approximately 8.5 MHz, application temperature range of 0℃ to 200℃, and capable of inspecting materials 3mm to 100mm thick.

Can the Thin Film sensor experience deterioration?: Degradation of sensor adhesives, cables, and pulsar scopes is possible, but will vary due to the environmental conditions which they are operating and/or exposed. Routine inspections is recommented to proactive identify any signs of degradation and implement remedial measures.

How about proofreading after installation?: If the temperature is measured with a pulsar scope, calibration is not necessary because the sound velocity is corrected each time the measurement is made. The technical validity of this operation has been evaluated by the Japan Power Generation Equipment Engineering Inspection Association.
