Profile: Pressure & Temparature Control Instruments Company are manufacturers of industrial dial thermometers and pressure gauges. Our instruments range from single board controls to microprocessor based products capable of computer communication & temperature sensors, including thermocouples, RTD and thermistor assemblies & accessories. Our product line includes temperature and pressure measuring systems & process protection devices. We supply temperature and pressure measuring gauges, temperature & pressure recorders, thermocouples, resistant temperature detectors, thermowells, vacuum gage & accessories. Our heatgauge mercury-in steel anti-vibration type dial thermometer operates on the principle of change of shape of bourden tube on account of internal pressure variation due to volume change of mercury inside caused by temperature, with patented spring supported case enabling the movement to withstand vibration suitable for diesel exhaust temperatures. Our temperature & pressure recorders are a high-accuracy temperature & pressure recorder with an internal battery and non-volatile memory for deployment at high depths. This is intended for moorings or other long-term, fixed-site applications, as well as shorter-term deployments on nets, towed vehicles, or ROVs. Calibration coefficients are stored in EEPROM, and uploaded data is in ASCII engineering units (°C & decibars).
