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

Replacement Parts
(4)42816
1/2-Unit Desiccant Bags (quantity of 10)
The 42816 desiccant is used to desiccate small subassemblies. For example, the KH20 Krypton Hygrometer and the base of the CR3000 Measurement and Control Datalogger each require two bags. Multi-packs are recommended for customers who need to desiccate multiple enclosures or systems.
Orderable5487
Velcro Strap, 1 in. x 9 in.
The 5487 may be purchased to replace a lost or damaged Velcro strap.
Orderable27373
14 to 28 AWG 5-Position Terminal Connector with Lever Nut
The 27373 facilitates connecting multiple wires into the same terminal, such as for SDI-12.
Orderable28878
Replacement Enclosure Humidity Indicator Card
The 28878 is a replacement humidity indicator card. It provides a visual reference of humidity level inside the case. Colored circles change color from blue to pink to indicate levels of 30%, 40%, and 50% relative humidity. Double sticky tape on the back of the card allows it to be easily secured to the case.

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.
