A150 Single Sensor Terminal Case, Vented with Desiccant

Overview

The A150 desiccated case is a small, self-contained junction box that allows a sensor to be connected to a continuation cable, a prewired-enclosure connector, or a CWS900 wireless-sensor connector.

Benefits and Features

  • Enables our CS450 and CS455 pressure transducers or other sensors that have a vented cable to be used in a wireless sensor network

Technical Description

The A150 consists of a terminal block mounted inside of junction box. A small vent is located on the bottom of the box. The vent includes a filter, which prevents moisture and contaminants from entering the unit while equalizing the interior air pressure to the current atmospheric pressure.

The A150 provides a mounting bracket for fastening it to an enclosure backplate. Alternatively a Velcro strap is included for mounting the A150 onto a user-supplied structure.

Compatibility

Sensors

The A150 is compatible with most sensors using six wires or less. Sensors with multiple ground wires can use the included 5-position lever nut to combine the grounds into a single wire connection. The A150 is often used with pressure transducers.

Wireless Interface

The -CWS cable termination option is used to connect the A150 to a CWS900-series interface, which allows the sensor to be part of a wireless sensor network. The CWS900-series interface is compatible with sensors that measure analog voltages, frequency, and pulse. The CWS900 series can also provide excitation voltage to a sensor through the A150.

Prewired Enclosures

The -PW cable termination option allows the A150 to be attached to a prewired enclosure. Prewired enclosures combine flexibility with ease of use.
