The Apollo Intelligent strain gage meter (IMS) accepts low level signals from a variety of bridge-type transducers, such as load cells, pressure transducers, torque transducers, etc. User selectable low (20 mV) and high (200 mV) input ranges and a stable, bridge excitation voltage, that is user selectable 5 V or 10 V at 60 mA, is provided. A two Hz, two pole, low pass filter coupled with programmable digital filtering can be tuned to match the characteristics of most processes. A digital tare (re-zero) operation can be performed at a touch of a button along with recall of process peak and valley (maximum/minimum) values. State of-the-art digital circuitry virtually eliminates errors due to drift. A full complement of option packages are available to fulfill many process applications. The indicator features a choice of two different scaling procedures which greatly simplifies initial set-up. A full 6-digit display accommodates virtually any process-engineering unit. English style display prompts aid the operator through set-up and operation. A front panel lock-out menu protects set-up data and operation modes from unauthorized personnel. Programmable remote input E1-CON and/or E2-CON, can be utilized to control a variety of totalizing, alarm control, display hold and tare operations. All set-up data is stored in E2PROM, which will hold data for a minimum of 10 years without power. As a standard feature, all units include an integrator (totalizer)10 Gigabit linearizer which can be used to totalize or integrate signals up to a maximum display value of 999,999. It features independent scaling and a low signal cut-out to suit a variety of signal integration applications. Additionally, nine slopes and offsets can easily be programmed to linearize transducers with non-linear outputs, such as square law devices. All readings are retained at power-down. Optional dual relays with parallel solid state outputs are fully programmable to operate in a wide variety of modes to suit many control or alarm applications. Optional 20 mA loop, bidirectional serial communications provides computer and printer interfacing to extend the capabilities of the indicator. More than one unit can be connected in the loop with other RLC products which have serial communications capabilities. An optional 4 to 20 mA or 0 to 10 VDC re-transmitted analog output can be scaled by the user to interface with a host of recorders, indicators and controllers. The indicator has several built-in diagnostic functions to alert operators of any malfunction. Extensive testing of noise interference mechanisms and full burn-in makes the indicator extremely reliable in industrial environments. The die cast front bezel meets NEMA 4/IP65 requirements for washdown applications. Plug-in style terminal blocks simplify installation wiring and change-outs.
