Desing highlights

Щуп для масс-спектрометрического течеискателя

The sniffer probe is set up of a flexible pencil-style casing equipped with a hermetically barb-latched metallic cup. Filtering discs are retained within the cup internal boring. The number of filter elements fitted is subject to the operating conditions (cleanliness of the working environment/objects) and normally can vary from 1 (clean environment) to 3 (contaminated conditions). The factory default of 2 filter discs guarantees a reliable protection in most cases.

To replace the filter: unclick the cup off the casing applying a combined axial and rotational force by hand. The reverse assembly upon the filter replacement is facilitated in the same manner by rotating and pushing the cup onto the casing barb until it gets latched.

The ceramic-metal restrictor setting a specified sniffer probe flow rate is hermetically molded inside the casing. The sniffer head is connected to the leak detector coupling by the specified length of plastic tubing. The tubing and coupling element joint is user dismountable, providing for the manifold length trimming adjustment if needed.

The tubing may be pulled out of gland whenever the gland's ferrule is depressed. Once the length is trimmed, the tube may be tightly pushed back into the gland's aperture till the travel limit.

It is advisable to put a special needle type nozzle over the tapered sniffer cup end, in case a restricted space precision leak pinpointing is needed (medical syringe needles of various sizes are applicable as well). Alternatively, elastic cup (ordered separately) may be used to broaden the tracing footprint.

Scope of delivery

The standard sniffer probe set is delivered in a factory package as follows:

Probe with coupling

1 pcs.

Pinpoint needle (plastic cap protected)

1 pcs.

Spare filter disks

10 pcs.

Specific delivery set and technical specifications of each device are detailed on the package tag.

Extra filter disks as well as elastic cups and other spares can be supplied upon request.

Cost and production time

Probes are available in stock. Producing leak detector probe for custom pumping system takes two weeks.

To ensure continuity of measurements in the case of obstruction it is recommended to order a set of two probes.
