Model Summary
The document provides a summary of differential pressure transmitters for liquids, specifically the DPTL series. These transmitters are designed for use in air-conditioning, heating, and water systems, and can handle mildly corrosive substances. The models vary by measurement range and output type, either voltage or current.

Specifications
Performance: The transmitters have an accuracy of ±1% full scale, with a maximum static pressure of 21 bar. Overpressure limits are 6 bar for ranges 1 and 2.5 bar, and 16 bar for ranges 4 and 6 bar. The response time is 10 ms.
Technical Specifications: The devices measure in bar and operate in ambient temperatures from -10 to 50 °C, with medium temperatures from -10 to 80 °C. They are constructed with ceramic and stainless steel materials, and use EPDM for sealing. The electrical connector follows DIN 43650 standards.
Electrical: For current output models, the supply voltage is 15-24 VDC with a current consumption of max 20 mA, outputting 4-20 mA. Voltage output models require 15-24 VDC or 24 VAC, with power consumption of 0.37 W (VDC) or 0.9 W (VAC), outputting 0-10 V.

Conformance
The products comply with CE marking requirements, including EMC Directive 2014/30/EU, RoHS Directive 2011/65/EU, and WEEE Directive 2012/19/EU. The company is certified by DNV GL for ISO 9001 and ISO 14001 standards.

Model Generation
Models are generated by combining the product series (DPTL), measuring range (e.g., 0...2.5 bar), and output type (V for voltage, C for current). For example, DPTL-2,5-V indicates a voltage output model with a 0...2.5 bar range.
