Heise Dresser Hand Held Pressure Calibrator model: PTE-1
**This unit has been tested to specifications. Everything in pictures is included. Has slight cosmetic blemishes from normal use. See photos for further details.
The Heise PTE-1 handheld system introduces a new era in pressure calibration standards. This unique instrument measures pressure, temperature, flow, vacuum, leak, current, voltage and change-of-state for switch testing. A fully equipped PTE-1 system provides all calibration capabilities needed in virtually all pressure measurement and test applications. Each handheld system consists of a base unit and one or two Quick-Select pressure modules. An array of pressure modules is available to cover ranges from 0.25 inches H2O through 10,000 psi. Modules can be inter-changed quickly and easily without the use of tools. In addition to pressure measurement, Quick-Select interface modules are also available to allow the PTE-1 to measure temperature with common RTDs or thermocouple devices.
The Quick-Select Pressure Module
Each base unit can accommodate two pressure sensor modules simultaneously. Select from multiple modules which can be interchanged in seconds without the use of tools. When installed in the base unit, a pressure module becomes an integral part of the measurement system, thereby protecting the sensor from damage.

The Quick-Select Pressure Module
Quick-Select pressure modules are available in full-scale ranges from 0.25 inches H2O through 10,000 psi. Gauge, vacuum, absolute, differential or compound pressure ranges are available. Each base unit can accommodate two pressure sensor modules simultaneously. Select from multiple modules which can be interchanged in seconds without the use of tools. When installed in the base unit, a pressure module becomes an integral part of the measurement system, thereby protecting the sensor from damage. Any combination of Quick-Select pressure modules may be used or interchanged as needed in the lab or field. The HQS-1. Quick-Select low pressure module is based on a proprietary, Ashcroft Inc. engineered, variable-capacitance sensor. This sensor is available in ranges from 0/0.25 to 0/200 inches H2O. HQS-1 Quick-Select pressure modules are available in accuracies from 0.1% to 0.06% of span. These Quick-Select pressure modules are available for gauge, differential and compound measurement requirements. The variable-capacitance sensing element in the HQS-1 incorporates a micromachined silicon diaphragm. Silicon provides optimum repeatability with minimal hysteresis. The sensor is extremely stable, since the sputtered metal capacitance plates are molecularly bonded to the silicon. This design allows for the elimination of epoxies and other types of bonding and adhesive agents from the sensor assembly. The HQS-1 sensor is also extremely rugged. It can withstand extreme overpressure without significant error or calibration offset. In addition, the sensor is capable of withstanding significant shock and vibration without damage or loss of measurement output integrity.
The HQS-2 Quick-Select pressure module incorporates a piezoresistive, micromachined silicon sensor. These sensors are available in ranges from 0/100 inches H2O through 0/10,000 psi and are also offered in absolute, vacuum and compound variants.HQS-2 sensors are available for gauge and absolute pressure or vacuum measurement. 316 SS sensor isolation is provided on all ranges for applications involving fluids or corrosive gases. HQS-2 Quick-Select pressure modules are available in a variety of accuracies from 0.1% of span through 0.025% of span. Also Measure Temperature The HQS-RT1, HQS-RT2 and HQS-TC1 interface modules allow the PTE-1 to measure temperature with common RTD or thermocouple temperature measurement devices.
The Base Unit
The base unit provides access to the complete capabilities of the PTE-1 calibration system. These capabilities extend far beyond those of precision pressure measurement. The base unit contains a wide variety of application-specific firmware as well as the ability to measure both current and voltage inputs. In addition, this unit has the ability to interface the system with a computer, data acquisition system or dumb terminal via the standard RS-232 interface. Each base unit can accommodate two Quick-Select pressure modules simultaneously. In addition, the modules can be interchanged quickly and easily for on-the-fly system configuration as application requirements change.
