AcuDew, the new addition to the SHAW dewpoint transmitters range.
AcuDew is the latest addition to the range of dewpoint transmitters from Shaw Moisture Meters. Incorporating the SHAW moisture sensing technology and advanced electronics.
This 2-wire, loop powered transmitter with linear 4-20 mA signal, transmits to a control system over distances up to 1,000 metres (3,280 feet). Most importantly, without any loss of signal. The AcuDew dewpoint range covers an overall dewpoint of -120 °C to +20 °C (-184 °F to +68 °F). Various dewpoint ranges are available within this scope and colour coded accordingly for easy reference. Configuring the output units to display in your choice of selectable engineering unit is a simple process. For example, choose from °C dewpoint, °F dewpoint, ppm(v), ppb(v), g/m³ and lb/MMSCF. Shaw Moisture Meters will configure your transmitter in their calibration laboratory.
The AcuDew provides a protection rating of IP66 (NEMA 4X). Manufactured using robust stainless-steel construction methods and tested to withstand 35,000kPA (350bar) maximum pressure. The transmitter utilises a cable with a secure 5 pin M12 connector. Thereby reducing the time required for installation and maintenance of wiring systems.
This dewpoint transmitter includes the AutoCal feature as standard. Therefore, allowing users to check the span of the instrument and correct any deviation between annual laboratory calibrations.
AcuDew provides a protection rating of IP66 (NEMA 4X) and is fully compatible with the new range of single channel displays. Choose from AcuLoop, AcuVu and AcuTrak. AcuLoop plug in signal indicator for local display. The panel mount AcuVu with 4-20 mA retransmission and fully programmable alarms. The AcuTrak with additional onboard pressure dewpoint calculations and RS485 communications. AcuDew is also suitable for use with various sample systems such as the existing SU4 sample system and SWS sample system.
Easy to install, easy to operate, the reliable and accurate AcuDew dewpoint transmitter requires little or no maintenance.
Supplied ready to use with two metres of cable, instruction manual and a Certificate of Calibration traceable to National and International Humidity Standards.
SHAW dewpoint transmitters AcuDew and the intrinsically safe SDT-Ex are designed for the stringent demands of industrial applications and extreme environmental conditions. Utilising the industry standard, ultra high capacitance SHAW moisture sensing technology and advanced electronics.
Various dewpoint ranges are available, covering an overall range from -120 °C to +20 °C dewpoint (-184 °F to +68 °F). The 4-20 mA output of the dewpoint transmitter is configurable in °C dewpoint, °F dewpoint, ppm(v), g/m³ and lb/MMSCF.
The incorporated advanced electronics derive power from the 7-28 V DC non isolated power source and configured to output a linear, isolated, 4-20 mA signal for distances up to 1,000 metres. Due to the mechanics of the sensing technology, design and construction of the transmitter, SHAW dewpoint transmitters can cope with extreme environmental conditions.
The SDT-Ex dewpoint transmitter is certified intrinsically safe to ATEX standards, including CE and UKCA approvals, for use in hazardous areas, when using a signal isolator.
Designed, with the operator in mind, for reliable and accurate trace moisture measurements. The AcuDew and SDT-Ex are extremely easy to install and operate, requiring little or no maintenance.
