Our range of products include pressure transmitter 981, head mounted temperature transmitter, differential pressure transmitters, dpt-cr-mod series, flush diaphragm pressure transmitter, piezoresistive pressure transmitter and magnehelic differential pressure gauge.
Analogue pressure transmitter monitoring overpressure, vacuum or differential pressure of liquid and gaseous also aggressive media. The pressure measurement is carried out in difference to the atmospheric pressure (relative pressure).
Temperature transmittersprogrammable by NFC RTD / Thermocouples to 4..20mA
The transmitters for DIN/B head convert a signal acquired by temperature probes PT100, PT1000 or Ni100 (with 2-, 3- and 4-wire connections) or Thermocouples into a 4..20 mA signal (2-wire technology), current-loop. These converters ensure high accuracy on the reading scale with 16-bit conversion and possibility to rescale the output 4..20mA basing on input range.
Available also the version with galvanic isolation (cod. 2000.35.015).

Differential Pressure Transmitters, DPT-CR-MOD Series
pressure,temperature and humidity monitoring in cleanrooms
HK Instruments Oy
Maximum Working Pressure
Differential pressure transmitter for cleanroom environmental monitoring with Modbus communication DPT-CR-MOD is a differential pressure transmitter designed specially for cleanroom monitoring.
In addition to differential pressure, the device enables monitoring temperature and relative humidity. A 0…10 V voltage input of an external humidity and temperature transmitter can be connected to the input terminal of the device.
In this case, all three measured values (differential pressure, relative humidity, temperature) can be shown simultaneously on the display. Alternatively, a passive temperature sensor can be connected to the input terminal.
DPT-CR-MOD is compatible with Modbus serial communication protocol.

Working Principle: TFP-310 is made from high-quality silicon piezoresistive chip. All process connections of the flush pressure transmitter are made of stainless steel, fully welded and isolate the process medium from the pressure measuring instrument via a positive seal. The TFP-310 is precision engineered to fit food, pharmaceutical and chemical liquid pressure measurement. A wide range of process connection and electrical connection options are available to meet almost requirement.
Working Principle: TFP-40S is made from high-quality silicon piezoresistive sensor. The piezoresistive sensor is packaged in stainless steel housing. The TFP-40S is precision engineered to fit most industrial pressure measurement.The compact and rugged design makes these pressure transmitter suitable for applications including process control systems, hydraulic systems and valves, refrigeration and HVAC controls, level measurement and test equipment. A wide range of process connection and electrical connection options are available to meet almost requirement.
The magnehelic gauge uses an incredibly sensitive diaphragm that responds to changes in pressure. ... The pointer or dial that is connected to the diaphragm responds to the change in pressure between the two sides of the diaphragm giving the pressure reading.
PTL series pressure transmitters are used for pressure detection in liquids in heating and cooling systems.
PTL-Heat is used for pressure detection in non-condensing applications such as district heating or heat recovery systems, whereas PTL-Cool is designed for extreme conditions where condensation is a common problem. PTL-Cool has a two-layer protection for electronics. This is why the possible condensation does not harm the product.
PTL series products are also suitable for refrigerants and non-aggressive gases.
PTL-Heat series devices are commonly used in HVAC/R systems for:
Liquid heat exchangers
Air compressor systems
PTL-Cool series devices are commonly used in HVAC/R systems for:
