G133

Positek

Part no.: G133

Key Features

• CSA approved to: Class I, Zone 0

• Sensor Mounting: Flange or body clampsSpring loaded pushrod option available

• Available in any measurement range from 0-51mm to 0-100mm(for 2-50mm range see P103)

• Sealed to IP65/67 depending on connector/cable option

The intrinsically safe G133 is CSA approved for use in potentially explosive gas/vapour atmospheres. It is designed for a wide range of industrial applications and is ideal for OEMs seeking good sensor performance in situations where a mid-bodied sensor is required for operation in hazardous areas. The unit is compact and space-efficient, being responsive along almost its entire length, and like all Positek sensors provides a linear output proportional to displacement. Each unit is supplied with the output calibrated to the travel required by the customer, from 0-51mm to 0-100mm and with full EMC protection built in.

Overall performance, repeatability and stability are outstanding over a wide temperature range.

The sensor has a rugged stainless steel body and plunger. It is easy to install and set up, mounting options include flange and body clamps. The plunger can be supplied free or captive, with female M4 thread, or spring-loaded with a ball end. The G133 also offers a wide range of mechanical options, environmental sealing is to IP65 or IP67 depending on selected cable or connector options.

Positek intrinsically safe sensors are designed to be used with a galvanically isolated amplifier. Approved galvanic isolation amplifiers (G005) are available from Positek; there is a choice of 0.5-9.5V or 4-20mA transmission outputs.

The sensor can be installed with a cable length up to 1km between the sensor and the amplifier.

Availability and the Three-Legged Stool analogy at Everight

While they may be small, the role of rotary encoders in spacecraft is vital, demanding a balance between performance, reliability, and the unforgiving environment of space. From NASA’s Robonaut II to automated material handling systems on the International Space Station, Everight has worked with engineers to put rotary encoders into ‘the final frontier.’

Accuracy, Resolution and Repeatability

There are several key terms that are critical to specifying the optimal position sensor for a given application. This application note defines these key terms and how they relate to the sensor’s role in the overall system performance. It is important to consider that precision is very much a system issue and can be dominated by mechanical errors such as eccentricity. This paper discusses the most significant mechanical error for rotary applications (eccentricity) and presents eccentricity tolerant position sensor solutions.

Inductosyn: End of an Era, New Opportunities or Both?

Recently, obtaining the Inductosyn and components for maintenance has become more difficult. For decades the Inductosyn from Farrand Controls / Ruhle Companies sat near the top of the rotary sensor hierarchy. Providing sub 2 arcsec (0.5 mdeg) accuracies, it combined the robustness of a resolver with the performance of the best optical encoders. Despite its shortcomings, it found plenty of customers, from airborne infrared and radar systems, to telescopes, satellite communication antennae (SATCOM), machine tooling and low-pressure vacuum chambers.

How Getting Older is Changing Robotics

While it may be noble to develop robotics to help older demographics in society, companies small and large alike have good business reasons to do so. Roughly 10,000 Baby Boomers retire daily. These consumers not only have wants and needs but have worked their whole lives to create a nest egg to fund them. […]
