MICROMANOMETERS WITH PITOT TUBE THERMOMETERS HD2114P.0, HD2114P.2, HD2134P.0, HD2134P.2, Merk : DeltaOhm
Keterangan
The HD2114P.0 and HD2114P.2, HD2134P.0 and HD2134P.2 are portable micro-manometers using Pitot tubes and a large LCD display. They are used to perform measurements in the fi elds of air conditioning, heating and ventilation.They measure the differential pressure detected by a Pitot tube connected to the instrument inputs acquiring the wind speed and fl ow rate inside pipelines and vents. They also measure the temperature using a type K thermocouple sensor.The instruments can be used as thermometers, and can be employed with any kind of thermocouple K sensor if a standard miniature connector is used.
The HD2114P.2 and HD2134P.2 instruments are dataloggers. They memorize up to 36,000 samples which can be transferred from the instrument connected to a PC via the multi-standard RS232C serial port and USB 2.0. The storing interval, printing, and baud rate can be confi gured using the menu.They are also fi tted with an RS232C serial port and can transfer the acquired measurements to a PC or to a portable printer in real time.
The Max, Min and Avg function calculates the maximum, minimum or average values. Other functions include: the relative measurement REL, the HOLD func-tion, and the automatic turning off which can also be disabled.The instruments have IP67 protection degree.

Type K Thermocouple probes Accuracy of the thermocouple probesThe tolerance of a type of thermocouple corresponds to the maximum acceptable departure from the e.m.f. of any thermocouple of that type, with reference junc-tion at 0°C. The tolerance is expressed in degrees Celsius, preceded by the sign. The percentage tolerance is given by the ratio between the tolerance expressed in degrees Celsius and the measurement junction temperature, multiplied by one hundred. The thermocouples conforming to regulations ASTM E230 and CEI EN60584-2 must comply with one of the following tolerance levels, the values of which are reported in the table.
G I (special tolerances)
G II (normal tolerances)The tolerances refer to the expected thermocouple operating temperature, in agreement with the thermoelements’ diameter.
