Field instrumentation
Measurement of flow, level, pressure, temperature, analysis and other process parameters.
- Transmitters, switches, gauges and indicators
- HART and FOUNDATION Fieldbus devices
- Elements, thermowells, manifolds and remote seals
Engineering, supply and integration
We engineer, supply and integrate industrial electrical, instrumentation and control systems.
We define the requirement, specify the equipment, supply it, and support it after start-up.
SIMSAN is an engineering company first. Engineering defines what a plant actually needs, and that definition is what makes the equipment we supply and the systems we integrate fit the process.
Capabilities
Four disciplines, specified together
Instruments, controls, final elements and the equipment around them are specified as one system, not as four separate purchases.
Control and automation
PLC, PAC, DCS and SCADA systems, control room hardware and signal handling.
- IEC 61131-3 controllers and remote I/O
- Modbus, PROFIBUS DP, CANopen, Ethernet
- Barriers, isolators, converters and drives
Final control elements
Control valves, actuators, positioners, regulators and safety devices for the process line.
- Control, on/off and motorised valves
- Positioners, boosters and solenoid valves
- Safety valves, relief valves, rupture disks
Equipment and supply
Original, brand new equipment sourced through a vetted manufacturer and supplier database.
- Electrical equipment, drives and UPS
- Instrument bulk material and special cables
- Calibration and valve shop equipment
How a measurement becomes a control action
Instrumentation and control is one continuous chain. A process variable is sensed, converted, transmitted, compared against a target, acted on by a valve, and recorded.
Sense
A sensor in contact with the process responds to pressure, temperature, flow, level or composition.
Transmit
A transmitter converts that response into a 4 to 20 mA or HART signal for the control system.
Compare
A controller compares the measured value against the setpoint and calculates the correction the process needs.
Act
The output drives a positioner and valve, a drive, or an on/off device that changes the process.
Record
SCADA and recorders log the loop so operators can see, prove and improve plant performance.
What we do on a project
Engineering
Defining the real requirement before equipment is chosen, including the before sales engineering that turns an inquiry into a scope.
Procurement
Sourcing original, brand new equipment through vetted manufacturers, with manufacturer documentation intact.
Integration
Bringing instruments, controllers and networks together so they work as one system.
Installation
Placing and connecting equipment on site so it matches the engineered design.
Commissioning
Loop checking, calibration, tuning and start-up, taking the system from powered up to running.
Support
Manufacturer guarantee and warranty passed through unchanged, with training where a plant needs it.
Industries
The process industries SIMSAN works in, and the measurement and control problems each one brings.
Oil and Gas
High steam service, pipelines and refinery process units, where pressure, flow and safety devices work under demanding conditions.
Chemical and Petrochemical
Corrosive and erosive fluids, tight composition control, and instrumentation that has to survive the process it measures.
Mine and Metals
Steel above all, an area of long standing activity, with high temperature measurement and heavy plant control.
Power and Energy
Thermal, gas and combined cycle plants, where boiler, burner and steam loops carry the plant's whole output.
Renewable Energy
Clean and renewable generation, an area SIMSAN follows out of a commitment to environmental protection.
Sugar Cane and Side Products
One of the first areas of activity, with process measurement across milling, boiling, evaporation and utilities.
Technology
Measuring principles and platforms we work with
The measuring principles, protocols and control platforms SIMSAN specifies and supplies. Experience with a technology is not a distribution agreement.

Why SIMSAN
Engineering before equipment
The requirement is defined before anything is bought. That is what stops a supply project becoming an expensive collection of individually correct devices.
A supply chain you can check
Original, brand-new equipment from a vetted database of manufacturers and suppliers, held as new stock. That is how fake product is kept out.
Delivery is not the end
Manufacturer guarantee and warranty pass to the customer on the manufacturer's own terms, with installation, commissioning, start-up and training where the project needs them.
Tell us what the process needs
Send the requirement, however rough it is, and an engineer will work out what it actually specifies.
