Lee-Dickens Ltd

Precision electronic instrument for the integration of electrical quantities against time giving a 24 Volt DC pulse and an open collector output suitable for operation of an electro-mechanical impulse counter, etc. The BD400 can be used for any application where time-varying signals require integrating. For instance:- Flow, Mass Flow (Liquids, Solids or Gases), Electric Charge, etc.

An analogue computation/mathematical module which can handle up to six analogue (mA) inputs and carry out a number of mathematical functions before outputting a standard transmission voltage or current signal. The MicroMATH is microprocessor based and offers a comprehensive range of mathematical operands. The MicroMATH is programmable with the programming function resident in non-volatile memory. Connect the MicroMATH to a PC/terminal via a Lee-Dickens MicroLEAD and set up the algorithm required. This can be a simple addition of several inputs to a more complicated algorithm containing Constants, Conditional Transfer Commands, Straight Line Approximations, etc. For example, MicroMATH can easily handle Mass Flow Calculations in the one instrument or more complex algorithms using cascaded units.

General purpose low cost two wire gauge pressure transmitter ranged -1 to 0 Bar suitable for non-agressive media. Final price whilst stocks last.

Quadruple Level Trip Amplifier from a single process signal input. The trip action can be arranged so that the Alarm condition can be above (High Trip) or below (Low Trip) each of the set points, and that the relays can be either normally energised to de-energise in the Alarm condition (Fail-Safe), or normally de-energised to energise in the Alarm condition (Non Fail-Safe).

Quadruple level trip amplifiers operate from a single process input with a quadruple trip action which can be arranged so that the alarm conditions are triggered either above or below the defined set points. 

Relative humidity (RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest.

RTUs are intelligent microprocessor based remote terminal units, which are used to monitor and control the operation of equipment at a remote site

We manufacture a wide range of highly accurate sensors for testing relative humidity, process temperature, environmental temperature, levels and conductivity.
