Wilcoxon accelerometers for Zone 2 environments

A Wilcoxon Research product story
Edited by the Engineeringtalk editorial team Aug 3, 2009

Wilcoxon Research has announced the release of six Class I Division 2 (Zone 2) accelerometers and three compatible cable-connector assemblies suitable for Zone 2 environments.

The six sensors all have a sensitivity of 100mV/g, and a tight + 5 per cent sensitivity tolerance, commonly called general-purpose industrial accelerometers.

The standard top-exit model is the 786A-D2.

The standard side-exit model is the 787A-D2, which is also available with a metric M8 mounting stud, model 787A-M8-D2.

The 780A-D2 is a compact sensor ideal for portable data collection.

The integral cable model is the 786F-D2.

The 786T-D2 is a dual output model that senses both vibration and temperature.

Three compatible connector-cable assemblies, suitable for Class I Division 2 (Zone 2) environments, are also offered by Wilcoxon Research.

Each cable connector can be lock wired to prevent it from inadvertently backing off the sensor.

The R6D2-J9T2A mates a MILC-C-5015 style two-pin connector with a twisted pair, Teflon-jacketed cable for harsh, 200C industrial environments.

The R6D2-J10 mates a MIL-C-5015 two-pin connector with a twisted pair cable; the cable has an Enviroprene jacket, suited to 125C industrial environments.

The R6D2-J9T2A and R6D2-J10 are compatible with all of the Class I Division 2 (Zone 2) sensors except the 786T-D2.

The 786T-D2 sensor is compatible with the R6GD2-J9T3A, a three-pin connector and three-wire cable with Teflon jacket.

The sensors were approved by agencies in both North America and Europe.

CSA certified the six sensors to be rated for use in Class I Division 2, Groups A, B, C, D, E, F, G environments.

Kema approved the sensors for Atex operation in Class I Zone 2 AEx na IIC T4.

Class I Division 2 (Zone 2) certification is not available for cables, however, the R6D2-J9T2A, R6D2-J10, and R6GD2-J9T3A are deemed suitable for installation in hazardous areas.

The final installation certification of the cables is determined by the governing authority.
