APAR Control industrial automation and measurement instrumentation

Polish manufacturer APAR Control specializes in temperature, humidity and pressure measurement solutions since 1985. As part of the APISENS Group, the enterprise develops equipment for metallurgy, chemical processing, food and pharmaceutical plants.

Technical solutions provide high noise immunity and long-term signal stability.

The product range includes resistance temperature detectors, thermocouples, microprocessor PID controllers, galvanic isolators and digital data recorders. Instruments integrate seamlessly into plant automation networks via RS485 Modbus RTU serial fieldbus.

SCP and AR series immersion and cable temperature sensor engineering

SCP series cable probes feature thin-film platinum Pt100 elements of accuracy class B as well as NTC and PTC thermistors. Probes are sealed inside stainless steel tubes of AISI304 or AISI316. Lead wires receive silicone, fluoropolymer or fiberglass insulation for moisture and thermal protection.

For process tanks, ovens, autoclaves and pipelines, AR10x, AR13x, AR14x and AR15x head and immersion assemblies provide secure operation. Protective thermowells and compression fittings allow adjustable immersion depth, maintaining integrity under elevated process pressures.

AR6xx series microprocessor multi-channel PID temperature controllers

Universal controllers AR634 and AR654 provide precise thermal regulation across four independent loops. The instruments feature bright graphical displays, cycle timers and internal memory for recording temperature trends.

Direct connections for thermocouples and platinum resistance sensors are supported.

Output configurations include electromechanical relays, solid-state relay drivers and continuous 4..20 mA analog outputs. Automated tuning algorithms determine optimal PID parameters, minimizing settling time and overshoot without manual adjustments.

AR650 and AR692 compact panel meters and industrial thermal regulators

For panel mounting in boiler controls, drying tunnels, packaging machinery and extruders, compact regulators AR650, AR692 and AR630 provide standard enclosure dimensions. The units measure primary sensor signals, compare values with setpoints and govern heating elements.

An internal scalable analog output retransmits measured temperature to secondary displays or supervisory PLC inputs. IP65 front panel sealing protects internal electronics from airborne dust and moisture during facility washdown routines.

AR5xx series signal conditioning transmitters and humidity sensors

AR5xx series transmitters provide galvanic isolation and convert raw temperature sensor outputs into standardized 4..20 mA current loops or 0..10 V signals. Signal conditioners prevent distortion along extended cable runs subject to heavy industrial electromagnetic interference.

The lineup features wall-mounted and duct-mount humidity and temperature transmitters AR550 and AR553 for environmental chambers, warehouses and cleanroom ventilation. Semiconductor sensing elements maintain repeatability across broad temperature ranges.

Selection guidelines and technical verification for APAR instrumentation

Primary sensors, controllers and secondary instruments are selected according to model numbers, equipment nameplates or process documentation. Sensor specifications require element type (Pt100, NTC, thermocouple), sheath length, diameter, process thread and operating temperature limits.

For controllers and regulators, input channels, supply voltage and output module types are confirmed against project schematics. Components ship with complete commercial documentation, clear pricing and dependable freight transit.
