GE’s Bently Nevada offers a wide variety of seismic and acceleration sensors, each designed to handle harsh industrial environments, and many capable of being installed in hazardous areas when appropriate barriers are used.

The following sensors provide comparable performance to other seismic sensors, but allow for use at higher temperatures.

Characteristics and advantages

330450 high temperature acceleration sensor features include:

It has a fundamentally unique construction compared to other acceleration sensors and can be used at high temperatures (up to +400°C or +752°F)

The high-temperature sensing element and the signal regulating electronics are permanently connected by hard wire cables and can be installed in separate hot and cold zones

The 330750 and 330752 High Temperature governor systems (HTVS) have fundamentally different construction, allowing for use at higher temperatures.

The unique design isolates the sensing element from the signal conditioning electronics, and the two are permanently connected via hard wire cables.

Current versions of these sensors allow the sensor heads to be mounted on surfaces with temperatures up to +400°C (+752°F).

350900 High Temperature Speed and Acceleration Sensors (HTVAS) separate the high temperature sensing element from the signal regulating electronics and the two are permanently connected via a hard wire cable. This arrangement allows you to mount the sensing head on surfaces with temperatures up to +482 °C (+900 °F), while installing the signal regulating electronics in cooler locations. Eliminating the connection between the sensor head and its associated signal regulating electronics also eliminates a significant source of potential sensor failures (connector problems). This achieves an overall sensor system performance comparable to other housing-mounted vibration sensors, but allows for use at higher temperatures. The main features of 350900 HTVAS are as follows:
