Load Cell/Strain Gauge Signal Amplifier - Mains Powered - DIN Rail Mounting
Signal amplifier that will convert the input from a Load Cell or Strain Gauge (Full or Half Bridge) into a standard transmission voltage or current signal. The DIN380 supplies the transducer excitation voltage and then conditions the resulting mV signal. The DIN380 includes remote sensing input terminals to ensure that the correct voltage is applied at the transducer if it is remote from the conditioning device. The DIN380 includes as standard, zero and span potentiometers for site tuning (~:±10%) and a Resistor Test Facility to simulate a known weight/force.Request a Quote Supplied by Lee-Dickens Ltd -
Loop Powered Isolator
A 4 to 20mA signal isolator that requires no external power supply. The power for the isolator is derived from the input loop. Typically the MIN310 could be used to provide a second isolated 4 to 20mA from an existing isolated loop. This would then allow two non-isolated inputs (e.g. an RTU input and a local indicator input) to monitor the same 4 to 20mA loop. If the input loop was not isolated you would need to use either a BM320 (24 Volt DC powered) or a BD320 (230/115 Volt AC powered) dual output isolator.Request a Quote Supplied by Lee-Dickens Ltd -
Low Input Impedance Isolating Signal Converter - DIN Rail Mounting
Low input impedance (10 ohms) isolating signal converter for use in 4 to 20mA loops. The BM916 will convert the 4 to 20mA signal into standard active and passive (current sink) transmission voltage or current signals. The BM916 first conditions the signal before feeding it through an opto-isolating circuit. Both the input and the output stages of the instrument are powered from separate secondaries of the inverter maintaining 3 port isolation.Request a Quote Supplied by Lee-Dickens Ltd -
Mathematical Functions - Mains Powered - DIN Rail Mounting
The DIN500 consists of a multi-functional analogue computing circuit which is factory calibrated as either a divider, multiplier, squarer, square root extractor or rectangular weir lineariser. If the measured process variable is temperature dependent, such as flow for instance, then the DIN500 can also be factory calibrated to accept a temperature compensation input for mass flow computation.Request a Quote Supplied by Lee-Dickens Ltd -

Process Signal Integrator - Mains Powered - DIN Rail Mounting
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.Request a Quote Supplied by Lee-Dickens Ltd -
Quadruple Level Trip Amplifier - DC Powered - DIN Rail Mounting
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).Request a Quote Supplied by Lee-Dickens Ltd -

Relative Humidity
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.
