Telemetry
Systems
Lee-Dickens manufacture, install
and commission Telemetry Systems for Vendor Managed Inventory, Tank Monitoring,
NavAid Monitoring and other non-specific telemetry applications. Our Telemetry
Systems are designed to transfer analogue, pulse and digital signals between 2
locations, this is done via a number of different communication media. Please
visit our website for more information about Telemetry Systems. |

PROCESS EQUIPMENT DIVISION
The Process Equipment Division is involved in the design and manufacture of a
comprehensive range of Electronic Process Control and Monitoring
Instrumentation, including Signal Conditioning Equipment and Trip Amplifiers,
Sensors and Transmitters for Temperature, Humidity and Level, Digital Process
Indicators and Signal Multiplexers.
 The Level measurement range offered is based upon the well known 80 Series
Telstor and Tektor capacitance probes and controllers, and, the 81 Series
Noflote conductivity probes and controllers. Lee-Dickens purchased these ranges
from ABB in 2001. The range has been added to with new DIN rail mounting
controllers in the 81 Series Noflote range and a new two- wire transmitter
version of the Telstor continuous level measurement capacitance level probe –
the Telstor ADVANCE.
The Relative Humidity and Temperature programme at Lee-Dickens includes duct and
wall mounting devices suitable for environmental monitoring. We also produce
ATEX approved duct and wall mounting RH transmitters and RH probes with a remote
head.
The Process Equipment Division also provides a sub-contract service for bespoke
product or printed circuit board (pcb) design, prototype, manufacture and test
to customer requirements and specifications. We also provide an Obsolete
Instrument design service. Component and Product Obsolescence is becoming a
large problem and with our design service we can often provide a cost effective
solution. |

SYSTEMS
DIVISION
The Lee-Dickens’ Systems Division provides systems design, manufacture, supply,
installation, commissioning and setting to work of Telemetry and SCADA
(Supervisory Control and Data Acquisition) Systems, as well as other bespoke
electronic and software systems.
The Systems Division employs experienced Sales, Project and Software Engineering
staff to ensure the customers' needs are fully understood and to ensure the
solutions provided are cost effective, on time and in budget.
 Systems Development The System Division specialises in System Design,
Development and Integration. Many of our customers ask us to adapt our existing
equipment to interface with third party equipment, or to integrate a number of
types of equipment into a working solution. Our depth of experience in Project
Management and Engineering, along with our wide range of products means that we
are ideally placed to solve your problems.
Quality
Assurance Hardware and Software development is carried out in accordance
with procedures laid down in our Design Engineering Practices & Procedures (DEP&P)
Manual which is approved to ISO9001 and the software requirement of ISO9000-3
Tick-IT.
Master Station Software Our current range of Master Station software
includes
-
SITEWATCH NT which runs on Windows NT or Windows XP platforms and has an
active graphics HMI-
SITEWATCH 2000 which
runs on Windows 95 or Windows NT platforms offering text Human
Machine Interface-
SITEWATCH NX which is X-Windows compliant and runs on workstations utilising
the UNIX operating system.

REMOTE
TERMINAL UNITS
Remote Terminal Units (RTUs) A range of SITEWATCH microprocessor based
intelligent Remote Terminal Units (RTUs) are available to provide the "real
world" interface to plant and equipment to be monitored and controlled. The RTUs
can be configured and tailored to meet the applications requirements.
Communications between the Master Station and RTUs can be via leased lines,
private wires, fibre-optics, radio, microwave links or the Public Switched
Telephone Network (PSTN).

Solutions The
systems offered can be “Closed” for very secure environments,
Web-Based for global access in multi-national companies, or
networked for wide-area access when required. The systems can
provide alerts in many forms such as SMS, email or secure web-page
and these alerts can be prioritised. Once the data has been gathered
our data handling service can output the data in a multitude of
formats for inputting into “others” systems for further analysis.
Our experienced staff, the inherent reliability of our
electronic products and our realistic systems approach, ensures that
our clients receive the most cost-effective system to meet their
requirements.
