Impress Sensors and Systems are going to exhibit a range of products, including a multi-channel process controller, and Submersible hydrostatic level Transmitters, at WWEM (Water, WasteWater and Environmental Monitoring) Exhibition, to be conducted at Shropshire’s Telford International Centre, on November 10th and 11th, 2010, in stand 29. The spotlight would be on the SDI-12L Transmitter, which supplies a SDI-12 digital output, along with an embedded high accuracy temperature sensor, which could be put to use for depths of 200 m.
Submersible hydrostatic level transmitters
This device can employ either a ceramic pressure sensor, made out of marine-bronze, or a stainless steel pressure sensor, which is silicon based. Piezoresistive technology is utilized in both versions, to guarantee repeatability of measurements and long term stability. This sensor is appropriate for monitoring reservoir and river levels, borehole water levels, V-notch weir flow measurements, seawater and estuary levels, Tsunami and tidal monitoring systems, vessels and tanks in process plants, environmental monitoring and wave height measurement. The stainless steel model provides a greater resolution of pressure management (up to 12-13 Bit), and a very low signal-to-noise ratio, ensuring a seamless and accurate way of level measurement. The ceramic version is ideal for use in marine environments, where regular models are prone to corrosion. These units suit estuary, seawater and saline applications.
The other transmitters included in the Impress portfolio are SIC-rated and ATEX-approved level transmitters, for hazardous environments, and submersible transmitters for aggressive media, in PEEK, PVC and PVDF materials, and for chemical dosing, CIP and SIP process. Transmitters with flush diaphragms, for pasty or thick media, are also a part of the range. Exceedingly high pressure units can also be obtained to safeguard transmitters, in pipe or tank blockage conditions.
A demonstration on the CMC-99, a novel, portable, multiple-channel, touch screen controller, would also be available in the Impress Stand 29 of WWEM. This device is suitable for synchronized measurements and control, of a range of water and wastewater solutions. It also includes transitional pumping stations control and measurement. The CMC-99 offers a mind-boggling variety of Input and Output blends, to meet customized needs. The unit contains three card slots on the backside of the controller, each having a 16 I/O pin options, which assist the users to make a choice of Input and output, to match the application. It also includes a 24V DC digital input, which allows setting up of triggers and relays.
